The engaging portion 423 is, for example, a recess recessed inward in the radial direction from the side surface of the connecting member main body 421. In the state shown in FIG. 1, the engaging portion 423 is located on the front side of the connecting member locking portion 413.

移動端子部422は、接続部材本体421の後端部から径方向外方へと突出する。移動端子部422は、筐体10の内部に固定されている複数の端子部43よりも後側に位置する。図1に示す状態では、移動端子部422は、複数の端子部43と接触することにより、複数の端子部43と電気的に接続され、また、複数の端子部43を電気的に接続している。以下の説明では、図1に示す接続部材42の位置を、「第1位置」と呼ぶ。接続部材本体421の後端部と筐体10の後端面との間には、前後方向に延びる弾性部材56が配置される。弾性部材56は、接続部材42を前方へと押圧する。これにより、移動端子部422が、複数の端子部43に向けて押圧される。なお、端子部43の数は、1であってもよく、2以上であってもよい。 The moving terminal portion 422 projects radially outward from the rear end portion of the connecting member main body 421. The moving terminal portion 422 is located on the rear side of the plurality of terminal portions 43 fixed inside the housing 10. In the state shown in FIG. 1, the moving terminal portion 422 is electrically connected to the plurality of terminal portions 43 by coming into contact with the plurality of terminal portions 43, and the plurality of terminal portions 43 are electrically connected to each other. There is. In the following description, the position of the connecting member 42 shown in FIG. 1 is referred to as a "first position". An elastic member 56 extending in the front-rear direction is arranged between the rear end portion of the connecting member main body 421 and the rear end surface of the housing 10. The elastic member 56 presses the connecting member 42 forward. As a result, the moving terminal portion 422 is pressed toward the plurality of terminal portions 43. The number of terminal portions 43 may be 1, or may be 2 or more.

次に、スイッチ1の動作について、図2ないし図6を参照しつつ説明する。図2ないし図6は、スイッチ1の縦断面図である。図2は、作業者により押しボタン部2が、図1に示す基準位置から少し後方に押し込まれた状態を示す縦断面図である。図2に示す状態では、弾性部材51,52が前後方向に少し圧縮され、押しボタン部2がロータ部31の前面に接触している。なお、押圧部材3およびシャッタ部41の位置は、図1に示す基準位置から移動していない。また、接続部材42も、図1に示す第1位置から移動しておらず、複数の端子部43の接続状態は、電気的に接続されたON状態のままである。 Next, the operation of the switch 1 will be described with reference to FIGS. 2 to 6. 2 to 6 are vertical cross-sectional views of the switch 1. FIG. 2 is a vertical cross-sectional view showing a state in which the push button portion 2 is pushed slightly rearward from the reference position shown in FIG. 1 by an operator. In the state shown in FIG. 2, the elastic members 51 and 52 are slightly compressed in the front-rear direction, and the push button portion 2 is in contact with the front surface of the rotor portion 31. The positions of the pressing member 3 and the shutter portion 41 have not moved from the reference positions shown in FIG. Further, the connecting member 42 has not moved from the first position shown in FIG. 1, and the connection state of the plurality of terminal portions 43 remains the electrically connected ON state.

押しボタン部2がさらに後方に押し込まれて図3に示す押込位置へと移動すると、押圧部材3およびシャッタ部41が、押しボタン部2により押圧されて後方へと移動し、図1および図2に示す基準位置よりも後側の押込位置に位置する。押圧部材3の係合部34は、押圧部材係止部44よりも後側に移動し、押圧部材係止部44と係合する。これにより、押圧部材3が押込位置にて係止される。 When the push button portion 2 is further pushed backward and moved to the pushing position shown in FIG. 3, the pressing member 3 and the shutter portion 41 are pressed by the push button portion 2 and moved backward, and FIGS. 1 and 2 It is located at the push-down position behind the reference position shown in. The engaging portion 34 of the pressing member 3 moves to the rear side of the pressing member locking portion 44 and engages with the pressing member locking portion 44. As a result, the pressing member 3 is locked at the pushing position.

また、接続部材42は、押圧部材3により押圧されて、上述の第1位置から後方へと移動し、図3に示す第2位置へと移動する。第2位置に位置する接続部材42では、移動端子部422が複数の端子部43から下側に離間する。これにより、複数の端子部43の接続状態は、電気的に非接続なOFF状態となる。すなわち、第2位置における接続部材42と複数の端子部43との接続状態は、第1位置における当該接続状態と異なる。また、第2位置に位置する接続部材42では、係合部423が、シャッタ部41の接続部材係止部413と、前後方向の略同じ位置に位置する。 Further, the connecting member 42 is pressed by the pressing member 3 and moves rearward from the above-mentioned first position, and moves to the second position shown in FIG. In the connecting member 42 located at the second position, the moving terminal portion 422 is separated downward from the plurality of terminal portions 43. As a result, the connected state of the plurality of terminal portions 43 becomes an electrically non-connected OFF state. That is, the connection state between the connection member 42 and the plurality of terminal portions 43 at the second position is different from the connection state at the first position. Further, in the connecting member 42 located at the second position, the engaging portion 423 is located at substantially the same position in the front-rear direction as the connecting member locking portion 413 of the shutter portion 41.

押しボタン部2が押込位置へと移動する際には、シャッタ支持部411の回転軸23よりも後側の部位が、筐体10の一部(具体的には、筐体10の内周面から径方向内方に突出する突出部)と接触して径方向内方へと押圧される。これにより、シャッタ支持部411が、回転軸23を中心として図3中の反時計回りに(すなわち、シャッタ支持部411の前端部が径方向外方へと移動する方向に)回転する。その結果、遮蔽部412が、ロータ部31の前側から径方向外方へと退避し、遮蔽部412によるロータ部31およびロータ鍵穴311の遮蔽が解除される。また、接続部材係止部413が、径方向内方へと移動し、第2位置に位置する接続部材42の係合部423と係合する(すなわち、第2位置に位置する接続部材42に接触する)。これにより、接続部材42が第2位置にて係止される。図3に示す状態では、弾性部材51,54〜56はそれぞれ圧縮されている。 When the push button portion 2 moves to the pushing position, the portion of the shutter support portion 411 behind the rotation shaft 23 is a part of the housing 10 (specifically, the inner peripheral surface of the housing 10). (Protruding portion protruding inward in the radial direction) is contacted and pressed inward in the radial direction. As a result, the shutter support portion 411 rotates counterclockwise in FIG. 3 (that is, in the direction in which the front end portion of the shutter support portion 411 moves outward in the radial direction) about the rotation shaft 23. As a result, the shielding portion 412 retracts radially outward from the front side of the rotor portion 31, and the shielding portion 412 releases the shielding of the rotor portion 31 and the rotor keyhole 311. Further, the connecting member locking portion 413 moves inward in the radial direction and engages with the engaging portion 423 of the connecting member 42 located at the second position (that is, the connecting member 42 located at the second position). Contact). As a result, the connecting member 42 is locked at the second position. In the state shown in FIG. 3, the elastic members 51, 54 to 56 are compressed, respectively.

続いて、図4に示すように、鍵91が、ボタン鍵穴211を介して押しボタン部2内へと挿入され、ロータ部31のロータ鍵穴311へと挿入される。そして、鍵91によりロータ部31が回転されることにより、係合部34が周方向に移動し、押圧部材係止部44から周方向に離間した位置に位置する。これにより、押圧部材係止部44による押圧部材3の係止が解除され、弾性部材51の復元力により、図5に示すように、押しボタン部2および押圧部材3が前方へと移動して基準位置に位置する。 Subsequently, as shown in FIG. 4, the key 91 is inserted into the push button portion 2 via the button keyhole 211, and is inserted into the rotor keyhole 311 of the rotor portion 31. Then, the rotor portion 31 is rotated by the key 91, so that the engaging portion 34 moves in the circumferential direction and is located at a position separated from the pressing member locking portion 44 in the circumferential direction. As a result, the pressing member 3 is released from being locked by the pressing member locking portion 44, and the restoring force of the elastic member 51 causes the push button portion 2 and the pressing member 3 to move forward as shown in FIG. Located in the reference position.

図5に示す状態では、シャッタ部41の遮蔽部412の先端部が、鍵91に接触している。このため、シャッタ部41は回転軸23を中心として図中の時計回りに回転することはできず、接続部材係止部413による接続部材42の係止は解除されない。したがって、押圧部材3による接続部材42の後方への押圧が解除されたにもかかわらず、接続部材42の位置は第2位置にて維持される。これにより、複数の端子部43の接続状態はOFF状態のまま維持される。すなわち、スイッチ1では、鍵91を挿入して回転させることにより、押しボタン部2は押込位置から基準位置に戻るが、複数の端子部43の接続状態は、ON状態には戻らず、OFF状態にて維持される。 In the state shown in FIG. 5, the tip of the shielding portion 412 of the shutter portion 41 is in contact with the key 91. Therefore, the shutter portion 41 cannot rotate clockwise in the drawing about the rotation shaft 23, and the connection member 42 cannot be unlocked by the connection member locking portion 413. Therefore, the position of the connecting member 42 is maintained at the second position even though the pressing of the connecting member 42 to the rear by the pressing member 3 is released. As a result, the connection state of the plurality of terminal portions 43 is maintained in the OFF state. That is, in the switch 1, the push button portion 2 returns from the pushed position to the reference position by inserting and rotating the key 91, but the connection state of the plurality of terminal portions 43 does not return to the ON state, but is in the OFF state. Is maintained at.

その後、図6に示すように、鍵91がロータ部31から抜き取られ、シャッタ部41から離間することにより、弾性部材54の復元力により、シャッタ部41が、回転軸23を中心として図中の時計回りに回転する。換言すれば、シャッタ支持部411が、回転軸23を中心として前端部が径方向内方へと移動する方向に回転する。これにより、遮蔽部412が、図5に示す押込位置から径方向内方へと移動し、ロータ部31の前側に挿入されて基準位置に位置する。その結果、ロータ部31およびロータ鍵穴311が、遮蔽部412により遮蔽される。 After that, as shown in FIG. 6, the key 91 is pulled out from the rotor portion 31 and separated from the shutter portion 41, so that the shutter portion 41 is centered on the rotation shaft 23 due to the restoring force of the elastic member 54. Rotate clockwise. In other words, the shutter support portion 411 rotates about the rotation shaft 23 in the direction in which the front end portion moves inward in the radial direction. As a result, the shielding portion 412 moves inward in the radial direction from the pushing position shown in FIG. 5, is inserted into the front side of the rotor portion 31, and is positioned at the reference position. As a result, the rotor portion 31 and the rotor keyhole 311 are shielded by the shielding portion 412.

また、シャッタ部41が図中の時計回りに回転すると、弾性部材55の復元力により、接続部材係止部413が径方向外方へと移動して接続部材42から離間する。これにより、接続部材42の係止が解除される。そして、弾性部材56の復元力により、接続部材42が、第2位置から前方へと移動して第1位置に位置する。これにより、接続部材42の移動端子部422が、複数の端子部43と接触し、複数の端子部43の接続状態が、OFF状態からON状態に戻る。 Further, when the shutter portion 41 rotates clockwise in the drawing, the connecting member locking portion 413 moves outward in the radial direction due to the restoring force of the elastic member 55 and separates from the connecting member 42. As a result, the connection member 42 is released from the lock. Then, due to the restoring force of the elastic member 56, the connecting member 42 moves forward from the second position and is positioned at the first position. As a result, the moving terminal portion 422 of the connecting member 42 comes into contact with the plurality of terminal portions 43, and the connection state of the plurality of terminal portions 43 returns from the OFF state to the ON state.

以上に説明したように、スイッチ1は、押しボタン部2と、押圧部材3と、シャッタ部41と、接続部材42と、端子部43とを備える。押しボタン部2は、基準位置から後方へと押し込み可能である。押しボタン部2の前面部21には、ボタン鍵穴211が設けられる。押圧部材3は、ボタン鍵穴211の後側に位置するロータ部31を有する。シャッタ部41は、ロータ部31の前側に位置し、ロータ部31を遮蔽する。接続部材42は、端子部43と接触することにより、端子部43と電気的に接続される。 As described above, the switch 1 includes a push button portion 2, a pressing member 3, a shutter portion 41, a connecting member 42, and a terminal portion 43. The push button portion 2 can be pushed backward from the reference position. A button keyhole 211 is provided on the front surface portion 21 of the push button portion 2. The pressing member 3 has a rotor portion 31 located behind the button keyhole 211. The shutter portion 41 is located on the front side of the rotor portion 31 and shields the rotor portion 31. The connecting member 42 is electrically connected to the terminal portion 43 by coming into contact with the terminal portion 43.

スイッチ1では、押しボタン部2が基準位置から後側の押込位置へと移動することにより、シャッタ部41がロータ部31の前側から退避する。また、押圧部材3は、押しボタン部2により押圧されて後方へと移動して係止される。さらに、接続部材42は、押圧部材3により押圧されて第1位置から後方へと移動して、端子部43との接続状態が第1位置とは異なる第2位置にて係止される。 In the switch 1, the push button portion 2 moves from the reference position to the rear push position, so that the shutter portion 41 retracts from the front side of the rotor portion 31. Further, the pressing member 3 is pressed by the push button portion 2 and moves rearward to be locked. Further, the connecting member 42 is pressed by the pressing member 3 and moves rearward from the first position, and is locked at a second position where the connection state with the terminal portion 43 is different from the first position.

次に、ボタン鍵穴211を介してロータ部31に鍵91が挿入されてロータ部31が回転されることにより、押圧部材3の係止が解除され、押圧部材3および押しボタン部2が前方へと移動する。押しボタン部2は基準位置に位置し、接続部材42の位置は第2位置にて維持される。そして、ロータ部31から鍵91が抜き取られることにより、接続部材42が前方へと移動して第1位置に位置する。また、シャッタ部41は、ロータ部31の前側に挿入される。 Next, the key 91 is inserted into the rotor portion 31 via the button keyhole 211, and the rotor portion 31 is rotated to release the locking of the pressing member 3, and the pressing member 3 and the push button portion 2 move forward. And move. The push button portion 2 is located at the reference position, and the position of the connecting member 42 is maintained at the second position. Then, when the key 91 is pulled out from the rotor portion 31, the connecting member 42 moves forward and is located at the first position. Further, the shutter portion 41 is inserted into the front side of the rotor portion 31.

このように、スイッチ1では、押しボタン部2を押し込んで接続部材42を第2位置へと位置させると(すなわち、OFF状態とすると)、鍵91を挿入してロータ部31を回転させた後、鍵91をロータ部31から抜き取るまで、接続部材42は第1位置に戻らず、接続状態はON状態に復帰しない。すなわち、鍵91をロータ部31から抜き取るまで、スイッチ1の操作対象である装置は、稼働可能な状態に復旧しない。換言すれば、鍵91をロータ部31から抜き取って初めて、当該装置は稼働可能な状態に復旧する。したがって、スイッチ1から鍵91が抜き取られずに放置されることを防止することができる。 In this way, in the switch 1, when the push button portion 2 is pushed in to position the connecting member 42 to the second position (that is, in the OFF state), the key 91 is inserted and the rotor portion 31 is rotated. The connecting member 42 does not return to the first position and the connected state does not return to the ON state until the key 91 is removed from the rotor portion 31. That is, the device to be operated by the switch 1 is not restored to an operable state until the key 91 is removed from the rotor unit 31. In other words, the device is restored to an operable state only after the key 91 is removed from the rotor section 31. Therefore, it is possible to prevent the key 91 from being left unplugged from the switch 1.

また、スイッチ1では、接続状態のON状態からOFF状態への移行と同期して、シャッタ部41によるロータ部31の遮蔽が解除され、接続状態のOFF状態からON状態への復帰と同期して、シャッタ部41によるロータ部31の遮蔽が行われる。これにより、接続状態がON状態のスイッチ1に、鍵91が挿入されることを防止することができる。 Further, in the switch 1, in synchronization with the transition from the ON state to the OFF state of the connected state, the shielding of the rotor unit 31 by the shutter unit 41 is released, and in synchronization with the return from the OFF state to the ON state of the connected state. , The rotor portion 31 is shielded by the shutter portion 41. As a result, it is possible to prevent the key 91 from being inserted into the switch 1 whose connection state is ON.

スイッチ1では、シャッタ部41が、シャッタ支持部411と、遮蔽部412と、接続部材係止部413とを備える。シャッタ支持部411は、押圧部材3の径方向外側にて前後方向に延びる。遮蔽部412は、シャッタ支持部411の前端部から径方向内方へと延びる。接続部材係止部413は、シャッタ支持部411の後端部に位置する。シャッタ支持部411は、押しボタン部2に設けられた前後方向に垂直な方向を向く回転軸23に回転可能に接続されている。 In the switch 1, the shutter portion 41 includes a shutter support portion 411, a shielding portion 412, and a connecting member locking portion 413. The shutter support portion 411 extends in the front-rear direction on the radial outer side of the pressing member 3. The shielding portion 412 extends radially inward from the front end portion of the shutter supporting portion 411. The connecting member locking portion 413 is located at the rear end of the shutter support portion 411. The shutter support portion 411 is rotatably connected to a rotation shaft 23 provided on the push button portion 2 and facing a direction perpendicular to the front-rear direction.

押しボタン部2が基準位置から押込位置へと移動する際には、シャッタ支持部411は、回転軸23を中心として、前端部が径方向外方へと移動する方向に回転する。これにより、遮蔽部412がロータ部31の前側から径方向外方へと退避し、接続部材係止部413が、径方向内方へと移動して、第2位置に位置する接続部材42に接触して接続部材42を係止する。 When the push button portion 2 moves from the reference position to the push position, the shutter support portion 411 rotates in a direction in which the front end portion moves outward in the radial direction with the rotation shaft 23 as the center. As a result, the shielding portion 412 retracts radially outward from the front side of the rotor portion 31, and the connecting member locking portion 413 moves radially inward to the connecting member 42 located at the second position. Contact to lock the connecting member 42.

また、ロータ部31から鍵91が抜き取られる際には、シャッタ支持部411は、回転軸23を中心として、前端部が径方向内方へと移動する方向に回転する。これにより、遮蔽部412が径方向内方へと移動してロータ部31の前側に挿入され、接続部材係止部413が径方向外方へと移動して接続部材42から離間し、接続部材42の係止が解除される。 When the key 91 is removed from the rotor portion 31, the shutter support portion 411 rotates about the rotation shaft 23 in a direction in which the front end portion moves inward in the radial direction. As a result, the shielding portion 412 moves inward in the radial direction and is inserted into the front side of the rotor portion 31, and the connecting member locking portion 413 moves outward in the radial direction and separates from the connecting member 42 to separate the connecting member. The lock of 42 is released.

このように、スイッチ1では、シャッタ部41において接続部材係止部413と遮蔽部412とが連動するため、接続部材42の第2位置から第1位置への移動(すなわち、接続状態のON状態への復帰)と、遮蔽部412によるロータ部31の遮蔽との同期を容易に実現することができる。 In this way, in the switch 1, since the connecting member locking portion 413 and the shielding portion 412 are interlocked in the shutter portion 41, the connecting member 42 is moved from the second position to the first position (that is, the connected state is ON). (Return to) can be easily synchronized with the shielding of the rotor unit 31 by the shielding unit 412.

なお、スイッチ1では、押圧部材3は、必ずしも1つの部材には限定されず、例えば、前後方向に並ぶ複数の部材を含んでいてもよい。例えば、押圧部材3は、ロータ部31が設けられる第1の部材と、当該第1の部材の後側に配置され、接続部材42を後方へと押圧する第2の部材とを含んでいてもよい。後述するスイッチ1a,1bにおいても同様である。 In the switch 1, the pressing member 3 is not necessarily limited to one member, and may include, for example, a plurality of members arranged in the front-rear direction. For example, the pressing member 3 may include a first member provided with the rotor portion 31 and a second member arranged behind the first member and pressing the connecting member 42 rearward. Good. The same applies to the switches 1a and 1b described later.

次に、本発明の第2の実施の形態に係るスイッチ1aについて、図7の縦断面図を参照しつつ説明する。図7に示すスイッチ1aは、後述する接続部材42aを第2位置にて係止する構造がスイッチ1と異なる点を除き、図1に示すスイッチ1と略同様の構造を有する。以下の説明では、上述のスイッチ1の構成と対応するスイッチ1aの各構成に同符号を付す。 Next, the switch 1a according to the second embodiment of the present invention will be described with reference to the vertical sectional view of FIG. 7. The switch 1a shown in FIG. 7 has substantially the same structure as the switch 1 shown in FIG. 1 except that the structure for locking the connection member 42a described later at the second position is different from that of the switch 1. In the following description, the same reference numerals are given to the configurations of the switch 1 and the corresponding configurations of the switch 1a.

図7に示すように、スイッチ1aでは、押圧部材3aは、図1に示す押圧部材本体32に代えて、ロータ部31の後側に略円柱状の内部空間320を有する押圧部材本体32aを備える。内部空間320は、後方に向けて開口している。押圧部材3aの他の構造は、図1に示す押圧部材3と略同様である。接続部材42aは、図1に示す接続部材本体421に代えて、略円柱状の内部空間420を有する接続部材本体421aを備える。内部空間420は、前方に向けて開口している。接続部材42aの他の構造は、図1に示す接続部材42と略同様である。シャッタ部41aは、接続部材係止部413に対応する構成が設けられない点を除き、図1に示すシャッタ部41と略同様の構造を有する。 As shown in FIG. 7, in the switch 1a, the pressing member 3a includes a pressing member main body 32a having a substantially columnar internal space 320 on the rear side of the rotor portion 31 instead of the pressing member main body 32 shown in FIG. .. The internal space 320 is open toward the rear. The other structure of the pressing member 3a is substantially the same as that of the pressing member 3 shown in FIG. The connecting member 42a includes a connecting member main body 421a having a substantially columnar internal space 420 instead of the connecting member main body 421 shown in FIG. The interior space 420 is open toward the front. The other structure of the connecting member 42a is substantially the same as that of the connecting member 42 shown in FIG. The shutter portion 41a has substantially the same structure as the shutter portion 41 shown in FIG. 1, except that a configuration corresponding to the connecting member locking portion 413 is not provided.

スイッチ1aは、係止部材45と、前弾性部材57とを備える。係止部材45は、前後方向に延びる略円柱状の部材である。係止部材45は、押圧部材3aの内部空間320および接続部材42aの内部空間420に配置される。前弾性部材57は、接続部材42aの内部空間420において、係止部材45の後側に配置される。前弾性部材57は、前後方向に延びる弾性部材である。前弾性部材57は、例えばコイルバネである。前弾性部材57は、コイルバネ以外の弾性部材(例えば、板バネ)であってもよい。 The switch 1a includes a locking member 45 and a front elastic member 57. The locking member 45 is a substantially columnar member extending in the front-rear direction. The locking member 45 is arranged in the internal space 320 of the pressing member 3a and the internal space 420 of the connecting member 42a. The front elastic member 57 is arranged behind the locking member 45 in the internal space 420 of the connecting member 42a. The front elastic member 57 is an elastic member extending in the front-rear direction. The front elastic member 57 is, for example, a coil spring. The front elastic member 57 may be an elastic member (for example, a leaf spring) other than the coil spring.

係止部材45は、係止部材本体451と、上フランジ部452と、下フランジ部453とを備える。係止部材本体451は、前後方向に延びる略円柱状の部位である。上フランジ部452および下フランジ部453はそれぞれ、回転軸J1を中心とする略円板状の部位である。上フランジ部452は、係止部材本体451の長手方向(すなわち、前後方向)の中央部から径方向外方に延びる。下フランジ部453は、係止部材本体451の下端部から径方向外方に延びる。上フランジ部452は、押圧部材3aの内部空間320に位置する。下フランジ部453は、接続部材42aの内部空間420に位置する。 The locking member 45 includes a locking member main body 451, an upper flange portion 452, and a lower flange portion 453. The locking member main body 451 is a substantially columnar portion extending in the front-rear direction. The upper flange portion 452 and the lower flange portion 453 are substantially disk-shaped portions centered on the rotation shaft J1, respectively. The upper flange portion 452 extends radially outward from the central portion in the longitudinal direction (that is, the front-rear direction) of the locking member main body 451. The lower flange portion 453 extends radially outward from the lower end portion of the locking member main body 451. The upper flange portion 452 is located in the internal space 320 of the pressing member 3a. The lower flange portion 453 is located in the internal space 420 of the connecting member 42a.

図7に示す状態では、上フランジ部452は内部空間320の前端部に位置し、下フランジ部453は内部空間420の前端部に位置する。係止部材本体451は、接続部材42aの内部空間420の前端部から前方に延び、押圧部材3aの内部空間320を経由してロータ部31の内部に至る。換言すれば、係止部材45は、ロータ部31の内部から後方に延びる。 In the state shown in FIG. 7, the upper flange portion 452 is located at the front end portion of the internal space 320, and the lower flange portion 453 is located at the front end portion of the internal space 420. The locking member main body 451 extends forward from the front end portion of the internal space 420 of the connecting member 42a, and reaches the inside of the rotor portion 31 via the internal space 320 of the pressing member 3a. In other words, the locking member 45 extends rearward from the inside of the rotor portion 31.

前弾性部材57は、圧縮状態にて係止部材45の後端部と接続部材42aの後端面との間に配置される。換言すれば、前弾性部材57は、係止部材45の後端部と接続部材42aとを接続する。上述のように、接続部材42aの後側には弾性部材56が設けられる。弾性部材56は、接続部材42aの後端面を挟んで、前弾性部材57と前後方向に並ぶ。本実施の形態における以下の説明では、弾性部材56を「後弾性部材56」と呼ぶ。後弾性部材56は、接続部材42aを前方へと押圧する。 The front elastic member 57 is arranged between the rear end portion of the locking member 45 and the rear end surface of the connecting member 42a in a compressed state. In other words, the front elastic member 57 connects the rear end portion of the locking member 45 and the connecting member 42a. As described above, the elastic member 56 is provided on the rear side of the connecting member 42a. The elastic member 56 is aligned with the front elastic member 57 in the front-rear direction with the rear end surface of the connecting member 42a interposed therebetween. In the following description of this embodiment, the elastic member 56 is referred to as a "post-elastic member 56". The rear elastic member 56 presses the connecting member 42a forward.

次に、スイッチ1aの動作について、図8ないし図12を参照しつつ説明する。図8ないし図12は、スイッチ1aの縦断面図である。図8は、作業者により押しボタン部2が、図7に示す基準位置から少し後方に押し込まれた状態を示す縦断面図である。図8に示す状態では、弾性部材51,52が前後方向に少し圧縮され、押しボタン部2がロータ部31の前面に接触している。なお、押圧部材3aおよびシャッタ部41aの位置は、図7に示す基準位置から移動していない。また、接続部材42aも、図7に示す第1位置から移動しておらず、複数の端子部43の接続状態は、電気的に接続されたON状態のままである。 Next, the operation of the switch 1a will be described with reference to FIGS. 8 to 12. 8 to 12 are vertical cross-sectional views of the switch 1a. FIG. 8 is a vertical cross-sectional view showing a state in which the push button portion 2 is pushed slightly rearward from the reference position shown in FIG. 7 by an operator. In the state shown in FIG. 8, the elastic members 51 and 52 are slightly compressed in the front-rear direction, and the push button portion 2 is in contact with the front surface of the rotor portion 31. The positions of the pressing member 3a and the shutter portion 41a have not moved from the reference positions shown in FIG. 7. Further, the connecting member 42a has not moved from the first position shown in FIG. 7, and the connection state of the plurality of terminal portions 43 remains the electrically connected ON state.

押しボタン部2がさらに後方に押し込まれて図9に示す押込位置へと移動すると、押圧部材3aおよびシャッタ部41aが、押しボタン部2により押圧されて後方へと移動し、図7および図8に示す基準位置よりも後側の押込位置に位置する。押圧部材3aの係合部34は、押圧部材係止部44よりも後側に移動し、押圧部材係止部44と係合する。これにより、押圧部材3aが押込位置にて係止される。 When the push button portion 2 is further pushed backward and moved to the pushing position shown in FIG. 9, the pressing member 3a and the shutter portion 41a are pressed by the push button portion 2 and moved backward, and FIGS. 7 and 8 show. It is located at the push-down position behind the reference position shown in. The engaging portion 34 of the pressing member 3a moves to the rear side of the pressing member locking portion 44 and engages with the pressing member locking portion 44. As a result, the pressing member 3a is locked at the pushing position.

また、押しボタン部2が押込位置へと移動する際には、シャッタ支持部411の回転軸23よりも後側の部位が、筐体10の一部(具体的には、筐体10の内周面から径方向内方に突出する突出部)と接触して径方向内方へと押圧される。これにより、シャッタ支持部411が、回転軸23を中心として図9中の反時計回りに(すなわち、シャッタ支持部411の前端部が径方向外方へと移動する方向に)回転する。その結果、遮蔽部412が、ロータ部31の前側から径方向外方へと退避し、遮蔽部412によるロータ部31およびロータ鍵穴311の遮蔽が解除される。 Further, when the push button portion 2 moves to the pushing position, the portion of the shutter support portion 411 behind the rotation shaft 23 is a part of the housing 10 (specifically, the inside of the housing 10). It comes into contact with a protruding portion that protrudes inward in the radial direction from the peripheral surface) and is pressed inward in the radial direction. As a result, the shutter support portion 411 rotates counterclockwise in FIG. 9 (that is, in the direction in which the front end portion of the shutter support portion 411 moves outward in the radial direction) about the rotation shaft 23. As a result, the shielding portion 412 retracts radially outward from the front side of the rotor portion 31, and the shielding portion 412 releases the shielding of the rotor portion 31 and the rotor keyhole 311.

接続部材42aは、押圧部材3aにより押圧されて、上述の第1位置から後方へと移動し、図9に示す第2位置へと移動する。上述のように、押圧部材3aが押圧部材係止部44により係止されているため、押圧部材3aにより後方へと押圧されている接続部材42aも、第2位置にて係止される。すなわち、押圧部材係止部44は、接続部材42aを第2位置に係止する係止部材でもある。第2位置に位置する接続部材42aでは、移動端子部422が複数の端子部43から下側に離間する。これにより、複数の端子部43の接続状態は、電気的に非接続なOFF状態となる。すなわち、第2位置における接続部材42aと複数の端子部43との接続状態は、第1位置における当該接続状態と異なる。 The connecting member 42a is pressed by the pressing member 3a and moves backward from the above-mentioned first position and moves to the second position shown in FIG. As described above, since the pressing member 3a is locked by the pressing member locking portion 44, the connecting member 42a pressed backward by the pressing member 3a is also locked at the second position. That is, the pressing member locking portion 44 is also a locking member that locks the connecting member 42a to the second position. In the connecting member 42a located at the second position, the moving terminal portion 422 is separated downward from the plurality of terminal portions 43. As a result, the connected state of the plurality of terminal portions 43 becomes an electrically non-connected OFF state. That is, the connection state between the connection member 42a and the plurality of terminal portions 43 at the second position is different from the connection state at the first position.

図9に示す状態では、係止部材45と押圧部材3aおよび接続部材42aとの相対位置は、図7および図8に示す状態から変化しておらず、係止部材45の下端部(すなわち、下フランジ部453)は、接続部材42aの内部空間420の前端部に位置している。また、弾性部材51,54、および、後弾性部材56はそれぞれ圧縮されている。 In the state shown in FIG. 9, the relative positions of the locking member 45, the pressing member 3a, and the connecting member 42a have not changed from the states shown in FIGS. 7 and 8, and the lower end portion of the locking member 45 (that is, that is, The lower flange portion 453) is located at the front end portion of the internal space 420 of the connecting member 42a. Further, the elastic members 51 and 54 and the rear elastic member 56 are compressed, respectively.

続いて、図10に示すように、鍵91が、ボタン鍵穴211を介して押しボタン部2内へと挿入され、ロータ部31のロータ鍵穴311へと挿入される。鍵91は、ロータ部31内に位置していた係止部材45の前端に接触し、係止部材45をロータ部31から後方へと押し出す。これにより、接続部材42aの内部空間420において、前弾性部材57が前後方向に圧縮される。 Subsequently, as shown in FIG. 10, the key 91 is inserted into the push button portion 2 via the button keyhole 211, and is inserted into the rotor keyhole 311 of the rotor portion 31. The key 91 comes into contact with the front end of the locking member 45 located in the rotor portion 31 and pushes the locking member 45 rearward from the rotor portion 31. As a result, the front elastic member 57 is compressed in the front-rear direction in the internal space 420 of the connecting member 42a.

そして、鍵91によりロータ部31が回転されることにより、係合部34が周方向に移動し、押圧部材係止部44から周方向に離間した位置に位置する。これにより、押圧部材係止部44による押圧部材3aの係止が解除され、弾性部材51の復元力により、図11に示すように、押しボタン部2および押圧部材3aが前方へと移動して基準位置に位置する。また、係止部材45も、押しボタン部2および押圧部材3aと共に前方へと移動する。上述のように、ロータ部31には鍵91が挿入された状態であるため、係止部材45は、図7に示す位置までは戻らず、係止部材45の下端部は、接続部材42aの内部空間420において、例えば前後方向の中央部に位置する。したがって、前弾性部材57は、図7に示す状態に比べて前後方向に圧縮されている。 Then, the rotor portion 31 is rotated by the key 91, so that the engaging portion 34 moves in the circumferential direction and is located at a position separated from the pressing member locking portion 44 in the circumferential direction. As a result, the pressing member 3a is released from the pressing member locking portion 44, and the restoring force of the elastic member 51 causes the push button portion 2 and the pressing member 3a to move forward as shown in FIG. Located in the reference position. Further, the locking member 45 also moves forward together with the push button portion 2 and the pressing member 3a. As described above, since the key 91 is inserted into the rotor portion 31, the locking member 45 does not return to the position shown in FIG. 7, and the lower end portion of the locking member 45 is the connecting member 42a. In the internal space 420, for example, it is located in the central portion in the front-rear direction. Therefore, the front elastic member 57 is compressed in the front-rear direction as compared with the state shown in FIG.

図11に示す状態では、前弾性部材57の復元力は、後弾性部材56の復元力よりも大きい。すなわち、前弾性部材57による接続部材42aを後方へと押圧する力は、後弾性部材56による接続部材42aを前方へと押圧する力よりも大きい。このため、接続部材42aの位置は、第2位置にて維持される。換言すれば、接続部材42aは、係止部材45および前弾性部材57により、第2位置にて係止される(すなわち、第2位置に付勢される)。したがって、複数の端子部43の接続状態はOFF状態のまま維持される。 In the state shown in FIG. 11, the restoring force of the front elastic member 57 is larger than the restoring force of the rear elastic member 56. That is, the force of the front elastic member 57 pressing the connecting member 42a backward is larger than the force of the rear elastic member 56 pressing the connecting member 42a forward. Therefore, the position of the connecting member 42a is maintained at the second position. In other words, the connecting member 42a is locked in the second position (that is, urged to the second position) by the locking member 45 and the front elastic member 57. Therefore, the connection state of the plurality of terminal portions 43 is maintained in the OFF state.

このように、スイッチ1aでは、スイッチ1と同様に、鍵91を挿入して回転させることにより、押しボタン部2は押込位置から基準位置に戻るが、複数の端子部43の接続状態は、ON状態には戻らず、OFF状態にて維持される。なお、図11に示す状態では、シャッタ部41aの遮蔽部412の先端部が、鍵91に接触している。このため、シャッタ部41aは回転軸23を中心として図中の時計回りに回転することはできない。 In this way, in the switch 1a, the push button portion 2 returns from the pushed position to the reference position by inserting and rotating the key 91 in the same manner as the switch 1, but the connection state of the plurality of terminal portions 43 is ON. It does not return to the state and is maintained in the OFF state. In the state shown in FIG. 11, the tip of the shielding portion 412 of the shutter portion 41a is in contact with the key 91. Therefore, the shutter portion 41a cannot rotate clockwise in the drawing about the rotation shaft 23.

その後、図12に示すように、鍵91がロータ部31から抜き取られることにより、前弾性部材57が前後方向に伸張する。係止部材45は、前弾性部材57により前方に押圧され、係止部材45の前端部はロータ部31の内部へと移動する。また、前弾性部材57が伸張することにより、前弾性部材57の復元力は、後弾性部材56の復元力よりも小さくなる。すなわち、前弾性部材57による接続部材42aを後方へと押圧する力が、後弾性部材56による接続部材42aを前方へと押圧する力よりも小さくなる。これにより、係止部材45による接続部材42aの係止が解除される(すなわち、係止部材45による接続部材42aの付勢が解除される)。そして、後弾性部材56の復元力により、接続部材42aが、第2位置から前方へと移動して第1位置に位置する。その結果、接続部材42aの移動端子部422が、複数の端子部43と接触し、複数の端子部43の接続状態が、OFF状態からON状態に戻る。 After that, as shown in FIG. 12, the key 91 is pulled out from the rotor portion 31, so that the front elastic member 57 extends in the front-rear direction. The locking member 45 is pressed forward by the front elastic member 57, and the front end portion of the locking member 45 moves into the rotor portion 31. Further, as the front elastic member 57 is stretched, the restoring force of the front elastic member 57 becomes smaller than the restoring force of the rear elastic member 56. That is, the force of the front elastic member 57 pressing the connecting member 42a backward is smaller than the force of the rear elastic member 56 pressing the connecting member 42a forward. As a result, the locking member 42a is released from being locked by the locking member 45 (that is, the urging of the connecting member 42a by the locking member 45 is released). Then, due to the restoring force of the rear elastic member 56, the connecting member 42a moves forward from the second position and is positioned at the first position. As a result, the moving terminal portion 422 of the connecting member 42a comes into contact with the plurality of terminal portions 43, and the connection state of the plurality of terminal portions 43 returns from the OFF state to the ON state.

スイッチ1aでは、鍵91がロータ部31から抜き取られ、シャッタ部41aから離間することにより、弾性部材54の復元力により、シャッタ部41aが、回転軸23を中心として図中の時計回りに回転する。換言すれば、シャッタ支持部411が、回転軸23を中心として前端部が径方向内方へと移動する方向に回転する。これにより、遮蔽部412が、図11に示す押込位置から径方向内方へと移動し、ロータ部31の前側に挿入されて基準位置に位置する。その結果、ロータ部31およびロータ鍵穴311が、遮蔽部412により遮蔽される。 In the switch 1a, the key 91 is pulled out from the rotor portion 31 and separated from the shutter portion 41a, so that the shutter portion 41a rotates clockwise in the drawing around the rotation shaft 23 due to the restoring force of the elastic member 54. .. In other words, the shutter support portion 411 rotates about the rotation shaft 23 in the direction in which the front end portion moves inward in the radial direction. As a result, the shielding portion 412 moves inward in the radial direction from the pushing position shown in FIG. 11, is inserted into the front side of the rotor portion 31, and is positioned at the reference position. As a result, the rotor portion 31 and the rotor keyhole 311 are shielded by the shielding portion 412.

以上に説明したように、スイッチ1aは、押しボタン部2と、押圧部材3aと、シャッタ部41aと、接続部材42aと、端子部43とを備える。押しボタン部2は、基準位置から後方へと押し込み可能である。押しボタン部2の前面部21には、ボタン鍵穴211が設けられる。押圧部材3aは、ボタン鍵穴211の後側に位置するロータ部31を有する。シャッタ部41aは、ロータ部31の前側に位置し、ロータ部31を遮蔽する。接続部材42aは、端子部43と接触することにより、端子部43と電気的に接続される。 As described above, the switch 1a includes a push button portion 2, a pressing member 3a, a shutter portion 41a, a connecting member 42a, and a terminal portion 43. The push button portion 2 can be pushed backward from the reference position. A button keyhole 211 is provided on the front surface portion 21 of the push button portion 2. The pressing member 3a has a rotor portion 31 located behind the button keyhole 211. The shutter portion 41a is located on the front side of the rotor portion 31 and shields the rotor portion 31. The connecting member 42a is electrically connected to the terminal portion 43 by coming into contact with the terminal portion 43.

スイッチ1aでは、押しボタン部2が基準位置から後側の押込位置へと移動することにより、シャッタ部41aがロータ部31の前側から退避する。また、押圧部材3aは、押しボタン部2により押圧されて後方へと移動して係止される。さらに、接続部材42aは、押圧部材3aにより押圧されて第1位置から後方へと移動して、端子部43との接続状態が第1位置とは異なる第2位置にて係止される。 In the switch 1a, the push button portion 2 moves from the reference position to the rear push position, so that the shutter portion 41a retracts from the front side of the rotor portion 31. Further, the pressing member 3a is pressed by the push button portion 2 and moves rearward to be locked. Further, the connecting member 42a is pressed by the pressing member 3a and moves rearward from the first position, and is locked at a second position where the connection state with the terminal portion 43 is different from the first position.

次に、ボタン鍵穴211を介してロータ部31に鍵91が挿入されてロータ部31が回転されることにより、押圧部材3aの係止が解除され、押圧部材3aおよび押しボタン部2が前方へと移動する。押しボタン部2は基準位置に位置し、接続部材42aの位置は第2位置にて維持される。そして、ロータ部31から鍵91が抜き取られることにより、接続部材42aが前方へと移動して第1位置に位置する。また、シャッタ部41aは、ロータ部31の前側に挿入される。 Next, the key 91 is inserted into the rotor portion 31 via the button keyhole 211, and the rotor portion 31 is rotated to release the locking of the pressing member 3a, so that the pressing member 3a and the push button portion 2 move forward. And move. The push button portion 2 is located at the reference position, and the position of the connecting member 42a is maintained at the second position. Then, when the key 91 is pulled out from the rotor portion 31, the connecting member 42a moves forward and is located at the first position. Further, the shutter portion 41a is inserted into the front side of the rotor portion 31.

このように、スイッチ1aでは、上述のスイッチ1と同様に、押しボタン部2を押し込んで接続部材42aを第2位置へと位置させると(すなわち、OFF状態とすると)、鍵91を挿入してロータ部31を回転させた後、鍵91をロータ部31から抜き取るまで、接続部材42aは第1位置に戻らず、接続状態はON状態に復帰しない。すなわち、鍵91をロータ部31から抜き取るまで、スイッチ1aの操作対象である装置は、稼働可能な状態に復旧しない。換言すれば、鍵91をロータ部31から抜き取って初めて、当該装置は稼働可能な状態に復旧する。したがって、スイッチ1aから鍵91が抜き取られずに放置されることを防止することができる。 As described above, in the switch 1a, when the push button portion 2 is pushed to position the connecting member 42a to the second position (that is, in the OFF state), the key 91 is inserted in the switch 1a as in the case of the switch 1 described above. After rotating the rotor portion 31, the connecting member 42a does not return to the first position and the connected state does not return to the ON state until the key 91 is pulled out from the rotor portion 31. That is, the device to be operated by the switch 1a is not restored to an operable state until the key 91 is removed from the rotor unit 31. In other words, the device is restored to an operable state only after the key 91 is removed from the rotor section 31. Therefore, it is possible to prevent the key 91 from being left unplugged from the switch 1a.

また、スイッチ1aでは、接続状態のON状態からOFF状態への移行と同期して、シャッタ部41aによるロータ部31の遮蔽が解除され、接続状態のOFF状態からON状態への復帰と同期して、シャッタ部41aによるロータ部31の遮蔽が行われる。これにより、接続状態がON状態のスイッチ1aに、鍵91が挿入されることを防止することができる。 Further, in the switch 1a, in synchronization with the transition from the ON state of the connected state to the OFF state, the shielding of the rotor unit 31 by the shutter unit 41a is released, and in synchronization with the return of the connected state from the OFF state to the ON state. , The rotor portion 31 is shielded by the shutter portion 41a. As a result, it is possible to prevent the key 91 from being inserted into the switch 1a whose connection state is ON.

上述のように、スイッチ1aは、係止部材45と、前弾性部材57と、後弾性部材56とをさらに備える。係止部材45は、ロータ部31の内部から後方に延びる。前弾性部材57は、係止部材45の後端部と接続部材42aとを接続する。後弾性部材56は、接続部材42aを前方へと押圧する。 As described above, the switch 1a further includes a locking member 45, a front elastic member 57, and a rear elastic member 56. The locking member 45 extends rearward from the inside of the rotor portion 31. The front elastic member 57 connects the rear end portion of the locking member 45 and the connecting member 42a. The rear elastic member 56 presses the connecting member 42a forward.

スイッチ1aでは、ボタン鍵穴211を介してロータ部31に鍵が挿入された状態では、係止部材45が鍵91によりロータ部31から後方へと押し出されて、前弾性部材57が前後方向に圧縮される。前弾性部材57による接続部材42aを後方へと押圧する力は、後弾性部材56による接続部材42aを前方へと押圧する力よりも大きい。このため、接続部材42aの位置は第2位置にて維持される。 In the switch 1a, when the key is inserted into the rotor portion 31 via the button keyhole 211, the locking member 45 is pushed backward from the rotor portion 31 by the key 91, and the front elastic member 57 is compressed in the front-rear direction. Will be done. The force of the front elastic member 57 pressing the connecting member 42a backward is larger than the force of the rear elastic member 56 pressing the connecting member 42a forward. Therefore, the position of the connecting member 42a is maintained at the second position.

また、スイッチ1aでは、鍵91がロータ部31が抜き取られる際に、前弾性部材57が前後方向に伸張し、前弾性部材57により係止部材45が前方に押圧されてロータ部31の内部へと移動する。前弾性部材57による接続部材42aを後方へと押圧する力は、後弾性部材56による接続部材42aを前方へと押圧する力よりも小さくなる。このため、接続部材42aが前方へと移動する。 Further, in the switch 1a, when the rotor portion 31 of the key 91 is pulled out, the front elastic member 57 extends in the front-rear direction, and the locking member 45 is pressed forward by the front elastic member 57 to the inside of the rotor portion 31. And move. The force of the front elastic member 57 pressing the connecting member 42a backward is smaller than the force of the rear elastic member 56 pressing the connecting member 42a forward. Therefore, the connecting member 42a moves forward.

スイッチ1aでは、接続部材42aを第2位置にて係止する(すなわち、第2位置に付勢する)係止部材45が、ロータ部31と前後方向に重なる位置に配置される。このため、スイッチ1aの径方向の大型化を抑制することができる。 In the switch 1a, the locking member 45 that locks the connecting member 42a at the second position (that is, urges the second position) is arranged at a position that overlaps the rotor portion 31 in the front-rear direction. Therefore, it is possible to suppress the increase in size of the switch 1a in the radial direction.

次に、本発明の第3の実施の形態に係るスイッチ1bについて、図13の縦断面図を参照しつつ説明する。図13に示すスイッチ1bは、接続部材42を第2位置にて係止する構造がスイッチ1と異なる点を除き、図1に示すスイッチ1と略同様の構造を有する。以下の説明では、上述のスイッチ1の構成と対応するスイッチ1bの各構成に同符号を付す。 Next, the switch 1b according to the third embodiment of the present invention will be described with reference to the vertical sectional view of FIG. The switch 1b shown in FIG. 13 has substantially the same structure as the switch 1 shown in FIG. 1 except that the structure for locking the connecting member 42 at the second position is different from that of the switch 1. In the following description, the same reference numerals are given to the respective configurations of the switch 1b corresponding to the above-described configuration of the switch 1.

図13に示すように、押圧部材3bは、図1に示す押圧部材3の各構成に加えて、押圧部材本体32から径方向外方へと突出する凸部である被検知部35をさらに備える。被検知部35は、例えば、前後方向において係合部34と略同じ位置に位置する。係合部34と被検知部35とは、例えば、押圧部材本体32を挟んで径方向の反対側に位置する。換言すれば、係合部34と被検知部35とは、周方向において180度ずれた位置に配置される。 As shown in FIG. 13, in addition to each configuration of the pressing member 3 shown in FIG. 1, the pressing member 3b further includes a detected portion 35 which is a convex portion protruding outward in the radial direction from the pressing member main body 32. .. The detected portion 35 is located, for example, at substantially the same position as the engaging portion 34 in the front-rear direction. The engaging portion 34 and the detected portion 35 are located, for example, on opposite sides in the radial direction with the pressing member main body 32 interposed therebetween. In other words, the engaging portion 34 and the detected portion 35 are arranged at positions displaced by 180 degrees in the circumferential direction.

シャッタ部41bは、ロータ部31の前側にて径方向に延びる略棒状の部材である。シャッタ部41bは、ボタン鍵穴211とロータ部31との間に配置される。スイッチ1bは、シャッタ部41bを当該径方向(すなわち、シャッタ部41bの長手方向)に移動するシャッタ部移動機構46をさらに備える。シャッタ部移動機構46は、ロータ部31の前側に対してシャッタ部41bを進退させる機構である。シャッタ部41bおよびシャッタ部移動機構46は、例えばソレノイドである。シャッタ部移動機構46は、押しボタン部2に固定される。 The shutter portion 41b is a substantially rod-shaped member extending in the radial direction on the front side of the rotor portion 31. The shutter portion 41b is arranged between the button keyhole 211 and the rotor portion 31. The switch 1b further includes a shutter portion moving mechanism 46 that moves the shutter portion 41b in the radial direction (that is, the longitudinal direction of the shutter portion 41b). The shutter unit moving mechanism 46 is a mechanism for advancing and retreating the shutter unit 41b with respect to the front side of the rotor unit 31. The shutter unit 41b and the shutter unit moving mechanism 46 are, for example, solenoids. The shutter unit moving mechanism 46 is fixed to the push button unit 2.

スイッチ1bは、接続部材42に接触して接続部材42を係止する接続部材係止部47をさらに備える。接続部材係止部47は、係止部本体471と、係止部移動機構472とを備える。係止部本体471は、接続部材42の係合部423近傍にて径方向に延びる略棒状の部材である。係止部本体471は、係合部423と周方向の略同じ位置に位置する。係止部移動機構472は、係止部本体471を上記径方向(すなわち、係止部本体471の長手方向)に移動する。係止部移動機構472は、接続部材42に向けて係止部本体471を進退させる機構である。接続部材係止部47は、例えばソレノイドである。係止部移動機構472は、筐体10に固定される。 The switch 1b further includes a connecting member locking portion 47 that contacts the connecting member 42 and locks the connecting member 42. The connecting member locking portion 47 includes a locking portion main body 471 and a locking portion moving mechanism 472. The locking portion main body 471 is a substantially rod-shaped member extending in the radial direction in the vicinity of the engaging portion 423 of the connecting member 42. The locking portion main body 471 is located at substantially the same position in the circumferential direction as the engaging portion 423. The locking portion moving mechanism 472 moves the locking portion main body 471 in the radial direction (that is, the longitudinal direction of the locking portion main body 471). The locking portion moving mechanism 472 is a mechanism for advancing and retreating the locking portion main body 471 toward the connecting member 42. The connecting member locking portion 47 is, for example, a solenoid. The locking portion moving mechanism 472 is fixed to the housing 10.

スイッチ1bは、さらに、第1検知部61と、第2検知部62と、制御部63とを備える。第1検知部61は、ボタン鍵穴211とロータ部31との間において、押しボタン部2に固定される。図13に示す例では、第1検知部61は、シャッタ部41bとロータ部31との間に配置される。第1検知部61は、ボタン鍵穴211とシャッタ部41bとの間に配置されてもよい。 The switch 1b further includes a first detection unit 61, a second detection unit 62, and a control unit 63. The first detection unit 61 is fixed to the push button unit 2 between the button keyhole 211 and the rotor unit 31. In the example shown in FIG. 13, the first detection unit 61 is arranged between the shutter unit 41b and the rotor unit 31. The first detection unit 61 may be arranged between the button keyhole 211 and the shutter unit 41b.

第1検知部61は、ボタン鍵穴211からロータ部31に挿入される鍵の有無を検出する。換言すれば、第1検知部61は、ロータ部31の前側における鍵の有無を検出する。第1検知部61は、例えば、ボタン鍵穴211とロータ鍵穴311との間における鍵の移動経路に配置されたフォトインタラプタである。鍵が、第1検知部61よりも後側まで挿入されると、第1検知部61の光が鍵により遮られる。これにより、ロータ部31の前側に鍵が存在することが、第1検知部61により検知される。 The first detection unit 61 detects the presence or absence of a key inserted into the rotor unit 31 from the button keyhole 211. In other words, the first detection unit 61 detects the presence or absence of the key on the front side of the rotor unit 31. The first detection unit 61 is, for example, a photo interrupter arranged in a key movement path between the button keyhole 211 and the rotor keyhole 311. When the key is inserted beyond the first detection unit 61, the light of the first detection unit 61 is blocked by the key. As a result, the presence of the key on the front side of the rotor unit 31 is detected by the first detection unit 61.

第2検知部62は、押圧部材3bの被検知部35近傍において、筐体10に固定される。図13に示す例では、第2検知部62は、被検知部35の下側に配置される。第2検知部62は、押しボタン部2が上述の押込位置に位置しているか否かを検知する。第2検知部62は、例えばフォトインタラプタである。押しボタン部2が押込位置に位置する状態では、被検知部35が、第2検知部62と前後方向の同じ位置に位置し、第2検知部62の光が被検知部35により遮られる。これにより、押しボタン部2が押込位置に位置することが、第2検知部62により検知される。一方、押しボタン部2が基準位置に位置する状態では、被検知部35により第2検知部62の光が遮られないため、押しボタン部2が押込位置に位置していないことが検知される。 The second detection unit 62 is fixed to the housing 10 in the vicinity of the detected unit 35 of the pressing member 3b. In the example shown in FIG. 13, the second detection unit 62 is arranged below the detection unit 35. The second detection unit 62 detects whether or not the push button unit 2 is located at the above-mentioned push position. The second detection unit 62 is, for example, a photo interrupter. In the state where the push button unit 2 is located at the pushed position, the detected unit 35 is located at the same position in the front-rear direction as the second detected unit 62, and the light of the second detected unit 62 is blocked by the detected unit 35. As a result, the second detection unit 62 detects that the push button unit 2 is located at the push-button position. On the other hand, when the push button unit 2 is located at the reference position, the light of the second detection unit 62 is not blocked by the detected unit 35, so that it is detected that the push button unit 2 is not located at the push position. ..

制御部63は、シャッタ部移動機構46、接続部材係止部47、第1検知部61および第2検知部62に接続される。制御部63は、シャッタ部移動機構46、および、接続部材係止部47の係止部移動機構472を制御する。 The control unit 63 is connected to the shutter unit moving mechanism 46, the connecting member locking unit 47, the first detection unit 61, and the second detection unit 62. The control unit 63 controls the shutter unit moving mechanism 46 and the locking unit moving mechanism 472 of the connecting member locking unit 47.

次に、スイッチ1bの動作について、図14ないし図18を参照しつつ説明する。図14ないし図18は、スイッチ1bの縦断面図である。図14は、作業者により押しボタン部2が、図13に示す基準位置から少し後方に押し込まれた状態を示す縦断面図である。図14に示す状態では、弾性部材51,52が前後方向に少し圧縮され、押しボタン部2がロータ部31の前面に接触している。なお、押圧部材3bの位置は、図13に示す基準位置から移動しておらず、シャッタ部41bはロータ部31の前側から移動していない。また、接続部材42も、図13に示す第1位置から移動しておらず、複数の端子部43の接続状態は、電気的に接続されたON状態のままである。 Next, the operation of the switch 1b will be described with reference to FIGS. 14 to 18. 14 to 18 are vertical cross-sectional views of the switch 1b. FIG. 14 is a vertical cross-sectional view showing a state in which the push button portion 2 is pushed slightly rearward from the reference position shown in FIG. 13 by the operator. In the state shown in FIG. 14, the elastic members 51 and 52 are slightly compressed in the front-rear direction, and the push button portion 2 is in contact with the front surface of the rotor portion 31. The position of the pressing member 3b has not moved from the reference position shown in FIG. 13, and the shutter portion 41b has not moved from the front side of the rotor portion 31. Further, the connecting member 42 has not moved from the first position shown in FIG. 13, and the connection state of the plurality of terminal portions 43 remains the electrically connected ON state.

押しボタン部2がさらに後方に押し込まれて図15に示す押込位置へと移動すると、押圧部材3bが、押しボタン部2により押圧されて後方へと移動し、図13および図14に示す基準位置よりも後側の押込位置に位置する。押圧部材3bの係合部34は、押圧部材係止部44よりも後側に移動し、押圧部材係止部44と係合する。これにより、押圧部材3bが押込位置にて係止される。 When the push button portion 2 is further pushed backward and moves to the pushing position shown in FIG. 15, the pressing member 3b is pressed by the push button portion 2 and moves backward, and the reference position shown in FIGS. 13 and 14 It is located at the push-back position on the rear side. The engaging portion 34 of the pressing member 3b moves to the rear side of the pressing member locking portion 44 and engages with the pressing member locking portion 44. As a result, the pressing member 3b is locked at the pushing position.

また、接続部材42は、押圧部材3bにより押圧されて、上述の第1位置から後方へと移動し、図15に示す第2位置へと移動する。第2位置に位置する接続部材42では、移動端子部422が複数の端子部43から下側に離間する。これにより、複数の端子部43の接続状態は、電気的に非接続なOFF状態となる。すなわち、第2位置における接続部材42と複数の端子部43との接続状態は、第1位置における当該接続状態と異なる。 Further, the connecting member 42 is pressed by the pressing member 3b, moves rearward from the above-mentioned first position, and moves to the second position shown in FIG. In the connecting member 42 located at the second position, the moving terminal portion 422 is separated downward from the plurality of terminal portions 43. As a result, the connected state of the plurality of terminal portions 43 becomes an electrically non-connected OFF state. That is, the connection state between the connection member 42 and the plurality of terminal portions 43 at the second position is different from the connection state at the first position.

押圧部材3bが押込位置に位置すると、押圧部材3bの被検知部35が第2検知部62により検知され、押圧部材3bが押込位置に位置しているという情報が、第2検知部62から制御部63へと送られる。制御部63は、当該情報を受け取ると、シャッタ部移動機構46および接続部材係止部47を制御する。これにより、シャッタ部移動機構46が駆動され、シャッタ部41bがロータ部31の前側から図中の左側(すなわち、径方向外方)へと退避される。これにより、シャッタ部41bによるロータ部31およびロータ鍵穴311の遮蔽が解除される。 When the pressing member 3b is located at the pushing position, the detected portion 35 of the pressing member 3b is detected by the second detecting unit 62, and the information that the pressing member 3b is located at the pushing position is controlled by the second detecting unit 62. It is sent to section 63. Upon receiving the information, the control unit 63 controls the shutter unit moving mechanism 46 and the connecting member locking unit 47. As a result, the shutter portion moving mechanism 46 is driven, and the shutter portion 41b is retracted from the front side of the rotor portion 31 to the left side in the drawing (that is, outward in the radial direction). As a result, the shutter portion 41b releases the shielding of the rotor portion 31 and the rotor keyhole 311.

また、接続部材係止部47において、係止部移動機構472が駆動され、係止部本体471が図中の右側(すなわち、径方向内方)へと移動する。係止部本体471の径方向内端部は、第2位置に位置する接続部材42の係合部423に挿入される。このように、第2位置に位置する接続部材42に接続部材係止部47が接触することにより、接続部材42が係止される。図15に示す状態では、弾性部材51,56はそれぞれ前後方向に圧縮されている。 Further, in the connecting member locking portion 47, the locking portion moving mechanism 472 is driven, and the locking portion main body 471 moves to the right side (that is, inward in the radial direction) in the drawing. The radial inner end of the locking portion body 471 is inserted into the engaging portion 423 of the connecting member 42 located at the second position. In this way, the connecting member 42 is locked by the contact of the connecting member locking portion 47 with the connecting member 42 located at the second position. In the state shown in FIG. 15, the elastic members 51 and 56 are compressed in the front-rear direction, respectively.

続いて、図16に示すように、鍵91が、ボタン鍵穴211を介して押しボタン部2内へと挿入され、ロータ部31のロータ鍵穴311へと挿入される。鍵91のロータ部31への挿入は、第1検知部61により検知されて制御部63へと通知される。 Subsequently, as shown in FIG. 16, the key 91 is inserted into the push button portion 2 via the button keyhole 211, and is inserted into the rotor keyhole 311 of the rotor portion 31. The insertion of the key 91 into the rotor unit 31 is detected by the first detection unit 61 and notified to the control unit 63.

次に、鍵91によりロータ部31が回転されることにより、係合部34が周方向に移動し、押圧部材係止部44から周方向に離間した位置に位置する。これにより、押圧部材係止部44による押圧部材3bの係止が解除され、弾性部材51の復元力により、図17に示すように、押しボタン部2および押圧部材3bが、押込位置から前方へと移動して基準位置に位置する。押圧部材3bが押込位置から前方へと移動すると、押圧部材3bの被検知部35が第2検知部62により検知されなくなる。そして、押しボタン部2および押圧部材3bが押込位置から前方へと移動した(すなわち、押込位置から離間した)という情報が、第2検知部62から制御部63へと送られる。 Next, when the rotor portion 31 is rotated by the key 91, the engaging portion 34 moves in the circumferential direction and is located at a position separated from the pressing member locking portion 44 in the circumferential direction. As a result, the pressing member 3b is released from being locked by the pressing member locking portion 44, and the restoring force of the elastic member 51 causes the push button portion 2 and the pressing member 3b to move forward from the pushing position as shown in FIG. And move to the reference position. When the pressing member 3b moves forward from the pushing position, the detected portion 35 of the pressing member 3b is not detected by the second detecting portion 62. Then, information that the push button unit 2 and the pressing member 3b have moved forward from the pushing position (that is, separated from the pushing position) is sent from the second detection unit 62 to the control unit 63.

図17に示す状態では、接続部材係止部47による接続部材42の係止は維持されている。したがって、押圧部材3bによる接続部材42の後方への押圧が解除されたにもかかわらず、接続部材42の位置は第2位置にて維持される。このため、複数の端子部43の接続状態はOFF状態のまま維持される。すなわち、スイッチ1bでは、鍵91を挿入して回転させることにより、押しボタン部2は押込位置から基準位置に戻るが、複数の端子部43の接続状態は、ON状態には戻らず、OFF状態にて維持される。 In the state shown in FIG. 17, the locking of the connecting member 42 by the connecting member locking portion 47 is maintained. Therefore, the position of the connecting member 42 is maintained at the second position even though the pressing member 3b releases the pressing of the connecting member 42 to the rear. Therefore, the connection state of the plurality of terminal portions 43 is maintained in the OFF state. That is, in the switch 1b, the push button portion 2 returns from the pushed position to the reference position by inserting and rotating the key 91, but the connection state of the plurality of terminal portions 43 does not return to the ON state but is in the OFF state. Is maintained at.

その後、図18に示すように、鍵91がロータ部31から抜き取られると、鍵91が第1検知部61により検知されなくなる。換言すれば、第1検知部61により、ロータ部31から鍵91が抜き取られたことが検知される。そして、第1検知部61から制御部63へと、鍵91が抜き取られたという情報が送られる。 After that, as shown in FIG. 18, when the key 91 is removed from the rotor unit 31, the key 91 is not detected by the first detection unit 61. In other words, the first detection unit 61 detects that the key 91 has been removed from the rotor unit 31. Then, the information that the key 91 has been removed is sent from the first detection unit 61 to the control unit 63.

制御部63は、ロータ部31への鍵91の挿入、押しボタン部2の押込位置からの移動、および、ロータ部31からの鍵91の抜き取りという3つの情報を、この順に受信すると、シャッタ部移動機構46および接続部材係止部47を制御する。これにより、シャッタ部移動機構46が駆動され、シャッタ部41bが図中の右側(すなわち、径方向内方)へと移動する。シャッタ部41bは、ロータ部31の前側に挿入され、ロータ部31およびロータ鍵穴311が、シャッタ部41bにより遮蔽される。 When the control unit 63 receives three pieces of information, that is, the insertion of the key 91 into the rotor unit 31, the movement of the push button unit 2 from the pushing position, and the extraction of the key 91 from the rotor unit 31, the shutter unit 63 receives the three information in this order. It controls the moving mechanism 46 and the connecting member locking portion 47. As a result, the shutter unit moving mechanism 46 is driven, and the shutter unit 41b moves to the right side (that is, inward in the radial direction) in the drawing. The shutter portion 41b is inserted in front of the rotor portion 31, and the rotor portion 31 and the rotor keyhole 311 are shielded by the shutter portion 41b.

また、接続部材係止部47において、係止部移動機構472が駆動され、係止部本体471が図中の左側(すなわち、径方向外方)へと移動する。これにより、接続部材係止部47が接続部材42から離間し、接続部材42の係止が解除される。そして、弾性部材56の復元力により、接続部材42が、第2位置から前方へと移動して第1位置に位置する。これにより、接続部材42の移動端子部422が、複数の端子部43と接触し、複数の端子部43の接続状態が、OFF状態からON状態に戻る。 Further, in the connecting member locking portion 47, the locking portion moving mechanism 472 is driven, and the locking portion main body 471 moves to the left side (that is, radially outward) in the drawing. As a result, the connecting member locking portion 47 is separated from the connecting member 42, and the locking of the connecting member 42 is released. Then, due to the restoring force of the elastic member 56, the connecting member 42 moves forward from the second position and is positioned at the first position. As a result, the moving terminal portion 422 of the connecting member 42 comes into contact with the plurality of terminal portions 43, and the connection state of the plurality of terminal portions 43 returns from the OFF state to the ON state.

以上に説明したように、スイッチ1bは、押しボタン部2と、押圧部材3bと、シャッタ部41bと、接続部材42と、端子部43とを備える。押しボタン部2は、基準位置から後方へと押し込み可能である。押しボタン部2の前面部21には、ボタン鍵穴211が設けられる。押圧部材3bは、ボタン鍵穴211の後側に位置するロータ部31を有する。シャッタ部41bは、ロータ部31の前側に位置し、ロータ部31を遮蔽する。接続部材42は、端子部43と接触することにより、端子部43と電気的に接続される。 As described above, the switch 1b includes a push button portion 2, a pressing member 3b, a shutter portion 41b, a connecting member 42, and a terminal portion 43. The push button portion 2 can be pushed backward from the reference position. A button keyhole 211 is provided on the front surface portion 21 of the push button portion 2. The pressing member 3b has a rotor portion 31 located behind the button keyhole 211. The shutter portion 41b is located on the front side of the rotor portion 31 and shields the rotor portion 31. The connecting member 42 is electrically connected to the terminal portion 43 by coming into contact with the terminal portion 43.

スイッチ1bでは、押しボタン部2が基準位置から後側の押込位置へと移動することにより、シャッタ部41bがロータ部31の前側から退避する。また、押圧部材3bは、押しボタン部2により押圧されて後方へと移動して係止される。さらに、接続部材42は、押圧部材3bにより押圧されて第1位置から後方へと移動して、端子部43との接続状態が第1位置とは異なる第2位置にて係止される。 In the switch 1b, the push button portion 2 moves from the reference position to the rear push position, so that the shutter portion 41b retracts from the front side of the rotor portion 31. Further, the pressing member 3b is pressed by the push button portion 2 and moves rearward to be locked. Further, the connecting member 42 is pressed by the pressing member 3b and moves rearward from the first position, and is locked at a second position where the connection state with the terminal portion 43 is different from the first position.

次に、ボタン鍵穴211を介してロータ部31に鍵91が挿入されてロータ部31が回転されることにより、押圧部材3bの係止が解除され、押圧部材3bおよび押しボタン部2が前方へと移動する。押しボタン部2は基準位置に位置し、接続部材42の位置は第2位置にて維持される。そして、ロータ部31から鍵91が抜き取られることにより、接続部材42が前方へと移動して第1位置に位置する。また、シャッタ部41bは、ロータ部31の前側に挿入される。 Next, the key 91 is inserted into the rotor portion 31 via the button keyhole 211 and the rotor portion 31 is rotated to release the locking of the pressing member 3b, and the pressing member 3b and the push button portion 2 move forward. And move. The push button portion 2 is located at the reference position, and the position of the connecting member 42 is maintained at the second position. Then, when the key 91 is pulled out from the rotor portion 31, the connecting member 42 moves forward and is located at the first position. Further, the shutter portion 41b is inserted in front of the rotor portion 31.

このように、スイッチ1bでは、上述のスイッチ1,1aと同様に、押しボタン部2を押し込んで接続部材42を第2位置へと位置させると(すなわち、OFF状態とすると)、鍵91を挿入してロータ部31を回転させた後、鍵91をロータ部31から抜き取るまで、接続部材42は第1位置に戻らず、接続状態はON状態に復帰しない。すなわち、鍵91をロータ部31から抜き取るまで、スイッチ1bの操作対象である装置は、稼働可能な状態に復旧しない。換言すれば、鍵91をロータ部31から抜き取って初めて、当該装置は稼働可能な状態に復旧する。したがって、スイッチ1bから鍵91が抜き取られずに放置されることを防止することができる。 In this way, in the switch 1b, when the push button portion 2 is pushed in to position the connecting member 42 to the second position (that is, in the OFF state), the key 91 is inserted in the same manner as in the switches 1 and 1a described above. After rotating the rotor portion 31, the connecting member 42 does not return to the first position and the connected state does not return to the ON state until the key 91 is pulled out from the rotor portion 31. That is, the device to be operated by the switch 1b is not restored to an operable state until the key 91 is removed from the rotor unit 31. In other words, the device is restored to an operable state only after the key 91 is removed from the rotor section 31. Therefore, it is possible to prevent the key 91 from being left unplugged from the switch 1b.

また、スイッチ1bでは、接続状態のON状態からOFF状態への移行と同期して、シャッタ部41bによるロータ部31の遮蔽が解除され、接続状態のOFF状態からON状態への復帰と同期して、シャッタ部41bによるロータ部31の遮蔽が行われる。これにより、接続状態がON状態のスイッチ1bに、鍵91が挿入されることを防止することができる。 Further, in the switch 1b, in synchronization with the transition from the ON state to the OFF state of the connected state, the shielding of the rotor unit 31 by the shutter unit 41b is released, and in synchronization with the return from the OFF state to the ON state of the connected state. , The rotor portion 31 is shielded by the shutter portion 41b. As a result, it is possible to prevent the key 91 from being inserted into the switch 1b whose connection state is ON.

上述のように、スイッチ1bは、第1検知部61と、第2検知部62と、シャッタ部移動機構46と、接続部材係止部47と、制御部63とをさらに備える。第1検知部61は、ロータ部31の前側における鍵91の有無を検知する。第2検知部62は、押しボタン部2が押込位置に位置しているか否かを検知する。シャッタ部移動機構46は、ロータ部31の前側に対してシャッタ部41bを進退させる。接続部材係止部47は、接続部材42に接触して接続部材42を係止する。制御部63は、シャッタ部移動機構46および接続部材係止部47を制御する。 As described above, the switch 1b further includes a first detection unit 61, a second detection unit 62, a shutter unit moving mechanism 46, a connection member locking unit 47, and a control unit 63. The first detection unit 61 detects the presence or absence of the key 91 on the front side of the rotor unit 31. The second detection unit 62 detects whether or not the push button unit 2 is located at the push position. The shutter unit moving mechanism 46 advances and retreats the shutter unit 41b with respect to the front side of the rotor unit 31. The connecting member locking portion 47 contacts the connecting member 42 and locks the connecting member 42. The control unit 63 controls the shutter unit moving mechanism 46 and the connecting member locking unit 47.

押しボタン部2が基準位置から押込位置へと移動したことが第2検知部62により検知されると、制御部63により、シャッタ部移動機構46および接続部材係止部47が制御される。これにより、シャッタ部41bが、ロータ部31の前側から退避される。また、接続部材係止部47が、第2位置に位置する接続部材42に接触して、接続部材42を係止する。 When the second detection unit 62 detects that the push button unit 2 has moved from the reference position to the push position, the control unit 63 controls the shutter unit moving mechanism 46 and the connecting member locking unit 47. As a result, the shutter portion 41b is retracted from the front side of the rotor portion 31. Further, the connecting member locking portion 47 comes into contact with the connecting member 42 located at the second position to lock the connecting member 42.

そして、ボタン鍵穴211を介してロータ部31に鍵91が挿入されたことが第1検知部61により検知され、鍵91によりロータ部31が回転されて押しボタン部2が押込位置から移動したことが第2検知部62により検知された後、ロータ部31から鍵91が抜き取られたことが第1検知部61により検知されると、制御部63により、シャッタ部移動機構46および接続部材係止部47が制御される。これにより、シャッタ部41bがロータ部31の前側に挿入され、接続部材係止部47が接続部材42から離間して、接続部材42の係止が解除される。 Then, the first detection unit 61 detects that the key 91 has been inserted into the rotor unit 31 via the button keyhole 211, and the rotor unit 31 is rotated by the key 91 to move the push button unit 2 from the pressing position. Is detected by the second detection unit 62, and when the first detection unit 61 detects that the key 91 has been removed from the rotor unit 31, the control unit 63 locks the shutter unit moving mechanism 46 and the connecting member. The unit 47 is controlled. As a result, the shutter portion 41b is inserted into the front side of the rotor portion 31, the connecting member locking portion 47 is separated from the connecting member 42, and the connecting member 42 is released from locking.

スイッチ1bでは、シャッタ部41bおよび接続部材係止部47の動作を小さくすることができる。その結果、スイッチ1bの大型化を抑制することができる。 In the switch 1b, the operation of the shutter portion 41b and the connecting member locking portion 47 can be reduced. As a result, it is possible to suppress the increase in size of the switch 1b.

上述のスイッチ1,1a,1bでは、様々な変更が可能である。 Various changes can be made with the switches 1, 1a and 1b described above.

例えば、スイッチ1bでは、第1検知部61および第2検知部62はそれぞれ、フォトインタラプタには限定されず、他の構造を有する様々な検知部であってもよい。また、シャッタ部41bおよびシャッタ部移動機構46、並びに、接続部材係止部47はそれぞれ、ソレノイドには限定されず、他の様々な機構であってもよい。 For example, in the switch 1b, the first detection unit 61 and the second detection unit 62 are not limited to the photo interrupter, and may be various detection units having other structures. Further, the shutter portion 41b, the shutter portion moving mechanism 46, and the connecting member locking portion 47 are not limited to the solenoid, and may be various other mechanisms.

スイッチ1では、接続部材42が第1位置に位置する状態で、複数の端子部43の接続状態がON状態であり、接続部材42が第2位置に位置する状態で、複数の端子部43の接続状態がOFF状態であるが、これには限定されない。例えば、接続部材42が第1位置に位置する状態で、複数の端子部43の接続状態がOFF状態であり、接続部材42が第2位置に位置する状態で、複数の端子部43の接続状態がON状態であってもよい。スイッチ1a,1bにおいても同様である。 In the switch 1, the connection member 42 is located at the first position, the connection state of the plurality of terminal portions 43 is ON, and the connection member 42 is located at the second position. The connection state is the OFF state, but the connection state is not limited to this. For example, the connection state of the plurality of terminal portions 43 is OFF when the connection member 42 is located at the first position, and the connection state of the plurality of terminal portions 43 is in the state where the connection member 42 is located at the second position. May be in the ON state. The same applies to the switches 1a and 1b.

上記実施の形態および各変形例における構成は、相互に矛盾しない限り適宜組み合わされてよい。 The above-described embodiment and the configurations in each modification may be appropriately combined as long as they do not conflict with each other.
