Description

スイッチswitch
　本発明は、スナップアクション機構を有するスイッチに関する。 The present invention relates to a switch having a snap action mechanism.
　従来、瞬時に接点の切り替えを行うスナップアクション機構を有するマイクロスイッチ等のスイッチが知られている。このようなスナップアクション機構を有するスイッチは、微小な間隔を設けて対向する接点機構を筐体の内部に有し、筐体に設けた操作部材を押圧して接点機構を瞬時に切り替える構成を有する。 Conventionally, switches such as microswitches that have a snap action mechanism that switches contacts instantly are known. A switch having such a snap action mechanism has a contact mechanism that faces each other with a minute gap, and has a configuration in which the contact mechanism is instantaneously switched by pressing an operation member provided in the case. .
　特許文献１は、アクチュエータ１７、コンタクトプレート１８及びコイルばね１９を備えるスイッチ機構部２と、共通端子６、常開固定端子７及び常閉固定端子８を備える接点パターン３と、が設置されたベース４と、ベース４の上に重ねて装着されるカバー５と、から構成されたケース１を備えるスナップアクション機構を有するスイッチを開示している。 Patent Document 1 discloses a base on which a switch mechanism unit 2 including an actuator 17, a contact plate 18 and a coil spring 19 and a contact pattern 3 including a common terminal 6, a normally open fixed terminal 7 and a normally closed fixed terminal 8 are installed. There is disclosed a switch having a snap action mechanism including a case 1 composed of a cover 4 mounted on the base 4 and a cover 5.
　特許文献１のスイッチは、スイッチ機構部２に外力が付与されていないときには、コイルばね１９のばね力によって可動接触片２３が常閉固定端子８に付勢されて接触している。ここで、スイッチ機構部２に外力が付与されると、操作部２０が押され、アクチュエータ１７が支持片２１を支点に押し下げられる。そして、このアクチュエータ１７の動きに連動して可動接触片２３が撓み始める。さらに、操作部２０が押し込まれると、可動接触片２３が凹部２５を支点に反転する。これにより、可動接点２６が常閉固定端子８から離れ、常開固定端子７に所定の圧力で接触する。また、スイッチ機構部２への外力が解除されると、コイルばね１９のばね力によって可動接触片２３が反転し、可動接点２６が常開固定端子７から離れて常閉固定端子８に接触し、元の位置に復帰する。 In the switch of Patent Document 1, when no external force is applied to the switch mechanism portion 2, the movable contact piece 23 is urged to contact the normally closed fixed terminal 8 by the spring force of the coil spring 19. Here, when an external force is applied to the switch mechanism unit 2, the operation unit 20 is pushed and the actuator 17 is pushed down with the support piece 21 as a fulcrum. Then, the movable contact piece 23 begins to bend in association with the movement of the actuator 17. Further, when the operating portion 20 is pushed in, the movable contact piece 23 is inverted around the recess 25 as a fulcrum. As a result, the movable contact 26 separates from the normally closed fixed terminal 8 and comes into contact with the normally open fixed terminal 7 at a predetermined pressure. When the external force applied to the switch mechanism unit 2 is released, the movable contact piece 23 is reversed by the spring force of the coil spring 19, and the movable contact 26 separates from the normally open fixed terminal 7 and comes into contact with the normally closed fixed terminal 8. , Return to the original position.
　このようなスイッチを車内等の塵や埃等の多い劣悪な環境下で使用する場合には、スイッチの内部に塵や埃等の異物が入り込み、その異物によって接点機構の接触信頼性を低下させる恐れがある。これに対して特許文献１のスイッチは、ベース４にカバー５を密着させる防護壁１３を設ける等によってケース１の密閉性を確保することにより、ケース１の外部から内部に異物が侵入することによる接触信頼性の低下を抑制している。 When such a switch is used in a bad environment such as in a car where there is a lot of dust and dirt, foreign matter such as dust and dirt enter the inside of the switch and the foreign matter reduces the contact reliability of the contact mechanism. There is a fear. On the other hand, in the switch of Patent Document 1, by providing a protective wall 13 for closely contacting the cover 5 with the base 4 and ensuring the airtightness of the case 1, foreign matter enters the inside of the case 1 from the outside. It suppresses the deterioration of contact reliability.
特開２０１５－１５３６８３号公報JP-A-2015-153683
　しかしながら、特許文献１においては、可動接触片２３が常閉固定端子８から常開固定端子７に又は常開固定端子７から常閉固定端子８に接続を切り替える過程で、可動接触片２３が一時的に常閉固定端子８と常開固定端子７との間の空間に位置する状態になるため、ケース１の密閉性が十分ではない場合、又は長期間に亘る振動等によってケース１の内部で破片等の異物を生じた場合には、可動接触片２３と常閉固定端子８又は常開固定端子７との間に異物が挟まる可能性があり、この場合には可動接触片２３と常閉固定端子８又は常開固定端子７との接触信頼性が低下するという課題を有する。 However, in Patent Document 1, the movable contact piece 23 is temporarily moved in the process of switching the connection of the movable contact piece 23 from the normally closed fixed terminal 8 to the normally open fixed terminal 7 or from the normally open fixed terminal 7 to the normally closed fixed terminal 8. Since it is located in the space between the normally-closed fixed terminal 8 and the normally-open fixed terminal 7, the case 1 is not sufficiently sealed, or the inside of the case 1 is vibrated for a long period of time or the like. When foreign matter such as debris is generated, the foreign matter may be caught between the movable contact piece 23 and the normally closed fixed terminal 8 or the normally open fixed terminal 7, and in this case, the movable contact piece 23 and the normally closed case are closed. There is a problem that contact reliability with the fixed terminal 8 or the normally open fixed terminal 7 is reduced.
　本発明の目的は、コンタクトがセルフクリーニングを行うことにより、接触信頼性を向上させることができるスイッチを提供することである。 An object of the present invention is to provide a switch that can improve contact reliability by making contacts self-cleaning.
　本発明に係るスイッチは、筐体と、前記筐体から外部に突出すると共に前記筐体に対して移動自在に設けられる操作部材と、前記筐体の内部に露出する固定接点と、前記筐体より外部に突出する端子部と、を各々が備え、前記固定接点が前記筐体の内底面に沿って互いに間隔を有して配列するように前記筐体に設けられる複数の固定コンタクトと、前記固定接点と接続する可動コンタクトを備え、前記固定接点の配列方向に沿ってスライドすることにより前記固定接点と前記可動コンタクトとの接続を切り替える駆動部材と、前記操作部材と前記駆動部材との間に設けられ、前記操作部材の移動に伴って前記駆動部材を前記配列方向の一方又は他方に付勢する第１の付勢部材と、を有する。 The switch according to the present invention includes a housing, an operating member that is provided outside the housing and is movably provided with respect to the housing, a fixed contact exposed inside the housing, and the housing.

A first urging member which is provided and urges the drive member in one or the other of the arrangement directions in accordance with the movement of the operation member.
　操作部材が操作されて移動することに伴って、駆動部材が第１の付勢部材によって配列方向の一方に付勢されてスライドすることにより、固定接点と可動コンタクトとの接続が切り替わり、その後に操作部材に対する操作が解除されて操作部材が移動することに伴って、駆動部材が第１の付勢部材によって配列方向の他方に付勢されてスライドすることにより、固定接点と可動コンタクトとの接続が切り替わる過程において、可動コンタクトが固定接点上をスライドすることによりセルフクリーニングを行う。 As the operating member is operated and moves, the driving member is biased by the first biasing member in one of the arrangement directions and slides, whereby the connection between the fixed contact and the movable contact is switched, and thereafter, When the operation member is released and the operation member moves, the drive member is urged by the first urging member to the other side in the arrangement direction and slides, thereby connecting the fixed contact and the movable contact. In the process of switching, the movable contact slides on the fixed contact to perform self-cleaning.
　本発明によれば、コンタクトがセルフクリーニングを行うことにより、接触信頼性を向上させることができる。 According to the present invention, the contact reliability can be improved by the self-cleaning of the contact.

　＜スイッチの組み立て方法＞
　本発明の実施形態に係るスイッチ１の組み立て方法につき、以下に詳細に説明する。 <How to assemble the switch>
A method for assembling the switch 1 according to the embodiment of the present invention will be described in detail below.
　ケース１０の対向壁部１２ａに設けた一対の規制部１３のうちの左方の規制部１３、及び対向壁部１２ｂに設けた一対の規制部１３のうちの左方の規制部１３に対して、スライダー９０の凹部９４を位置合わせしながら、スライダー９０をケース１０に対して上方から可動コンタクト１００ａ及び可動コンタクト１００ｂが内底面１０ａに当接するまで挿入する。 With respect to the left restricting part 13 of the pair of restricting parts 13 provided on the facing wall part 12a of the case 10 and the left restricting part 13 of the pair of restricting parts 13 provided on the facing wall part 12b. While aligning the concave portion 94 of the slider 90, the slider 90 is inserted into the case 10 from above until the movable contacts 100a and 100b contact the inner bottom surface 10a.
　次に、ケース１０に挿入したスライダー９０を少し下方に押圧しながら、ガイド部９１の上面が左方の規制部１３の下面に対向する状態になるまでスライダー９０を右方にスライドさせる。これにより、ケース１０に対するスライダー９０の上方への移動を規制部１３によって規制することにより、ケース１０にスライダー９０を仮保持させることができる。 Next, while pushing the slider 90 inserted in the case 10 slightly downward, the slider 90 is slid rightward until the upper surface of the guide portion 91 faces the lower surface of the left regulating portion 13. Thus, by restricting the upward movement of the slider 90 with respect to the case 10 by the restricting portion 13, it is possible to temporarily hold the slider 90 in the case 10.
　次に、ケース１０の保持孔１１１に対してばね４０の下端を挿入して、ばね４０をケース１０に保持させる。これにより、ケース１０は、可動コンタクト１００ａ及び可動コンタクト１００ｂを備えたスライダー９０と、ばね４０と、を保持した状態になる。 Next, the lower end of the spring 40 is inserted into the holding hole 111 of the case 10 to hold the spring 40 in the case 10. As a result, the case 10 is in a state of holding the slider 40 including the movable contact 100a and the movable contact 100b and the spring 40.
　また、ケース１０とは別にカバー２０を裏返して、レバー３０を挿通孔２１に挿通させると共にラバー３５の挿通孔３６に挿通させる。 Separately from the case 10, the cover 20 is turned over so that the lever 30 is inserted into the insertion hole 21 and the insertion hole 36 of the rubber 35.
　次に、ラバー３５をレバー３０の保持部３２に保持させると共にラバー３５の下端側に対して保持部２２を加締めて、ラバー３５をレバー３０とカバー２０とに保持させる。 Next, the rubber 35 is held by the holding portion 32 of the lever 30, and the holding portion 22 is swaged to the lower end side of the rubber 35, so that the rubber 35 is held by the lever 30 and the cover 20.
　次に、予めレバー３０と一体にしておいたフック５０の係止部５３に対して、ばね７０の係止部７２を係止させる。 Next, the locking portion 72 of the spring 70 is locked to the locking portion 53 of the hook 50 that is previously integrated with the lever 30.
　次に、ばね７０の係止部７１をアクチュエータ６０の係止孔６１１に係止させると共に、アクチュエータ６０の分岐部６２を突出部２３の傾斜面２３ａに当接させる。これにより、裏返されたカバー２０は、レバー３０、ラバー３５、フック５０、アクチュエータ６０及びばね７０を保持した状態になる。 Next, the locking portion 71 of the spring 70 is locked in the locking hole 611 of the actuator 60, and the branch portion 62 of the actuator 60 is brought into contact with the inclined surface 23a of the protruding portion 23. As a result, the cover 20, which has been turned over, is in a state of holding the lever 30, the rubber 35, the hook 50, the actuator 60, and the spring 70.
　次に、裏返したカバー２０を、アクチュエータ６０を押さえた状態で裏返す前の元の向きに戻してケース１０の上方を覆うように位置合わせしながら、レバー３０の突出部３１にばね４０の上端を保持させると共に、アクチュエータ６０の係合部６３をスライダー９０の係合凹部９５に移動可能に係合させる。この際に、スライダー９０の係合凹部９５に対してアクチュエータ６０の係合部６３が可動に必要なクリアランスを有して係合している。これにより、アクチュエータ６０に生じる微細な振動を係合凹部９５と係合部６３との係合部分で吸収することができるため、アクチュエータ６０に生じる微細な振動がスライダー９０に伝わり難くすることができ、可動接点１０１と固定接点８７との接続信頼性を向上させることができる。 Next, while returning the cover 20 which has been turned upside down to the original direction before turning over while holding the actuator 60 and aligning so as to cover the upper side of the case 10, the upper end of the spring 40 is attached to the protrusion 31 of the lever 30. While being held, the engaging portion 63 of the actuator 60 is movably engaged with the engaging concave portion 95 of the slider 90. At this time, the engaging portion 63 of the actuator 60 is engaged with the engaging concave portion 95 of the slider 90 with a clearance required for movement. As a result, since the minute vibration generated in the actuator 60 can be absorbed by the engaging portion between the engaging concave portion 95 and the engaging portion 63, the minute vibration generated in the actuator 60 can be made difficult to be transmitted to the slider 90. The connection reliability between the movable contact 101 and the fixed contact 87 can be improved.
　次に、ケース１０とカバー２０とを溶接又は嵌合等によって一体に接続することにより、スイッチ１が完成する。このように、レバー３０、ラバー３５、ばね７０及びアクチュエータ６０を内部に保持するカバー２０と、ばね４０及びスライダー９０を内部に保持するケース１０と、を接続してスイッチ１を構成することができるため、組み立てを容易にすることができる。 Next, the switch 1 is completed by integrally connecting the case 10 and the cover 20 by welding or fitting. As described above, the switch 1 can be configured by connecting the cover 20, which internally holds the lever 30, the rubber 35, the spring 70, and the actuator 60, and the case 10, which internally holds the spring 40 and the slider 90. Therefore, the assembly can be facilitated.
　上記の方法によって組み立てたスイッチ１において、スライダー９０はガイド部９１がケース１０に設けた規制部１３によって下方に押圧されているため、可動コンタクト１００ａが固定コンタクト群８０ａの固定接点８７に圧接して接続すると共に、可動コンタクト１００ｂが固定コンタクト群８０ｂの固定接点８７に圧接して接続することにより、可動コンタクト１００ａと固定コンタクト群８０ａとの接触信頼性を向上させることができると共に、可動コンタクト１００ｂと固定コンタクト群８０ｂとの接触信頼性を向上させることができる。 In the switch 1 assembled by the above method, since the guide portion 91 of the slider 90 is pressed downward by the regulating portion 13 provided in the case 10, the movable contact 100a is brought into pressure contact with the fixed contact 87 of the fixed contact group 80a. By connecting the movable contact 100b to the fixed contact 87 of the fixed contact group 80b while pressing the connection, the contact reliability between the movable contact 100a and the fixed contact group 80a can be improved, and the movable contact 100b and The contact reliability with the fixed contact group 80b can be improved.
　また、スイッチ１の組み立て時にケース１０に対してスライダー９０を仮保持させるための部材と、可動接点１０１を固定接点８７に圧接させるための部材と、をケース１０に設けた規制部１３で兼用させることができる。 Further, the restricting portion 13 provided in the case 10 also serves as a member for temporarily holding the slider 90 with respect to the case 10 during assembly of the switch 1 and a member for pressing the movable contact 101 to the fixed contact 87. be able to.
　また、固定接点８７を内底面１０ａに沿って配列することにより回路パターンを平面上に形成することができるため、従来のマイクロスイッチ等の接点機構に比べて、スイッチ回路を単純な構成にすることができる。 Further, since the circuit pattern can be formed on the plane by arranging the fixed contacts 87 along the inner bottom surface 10a, the switch circuit has a simpler structure than the conventional contact mechanism such as a micro switch. You can
　＜スイッチの動作＞
　本発明の実施形態に係るスイッチ１の動作につき、図４及び図１５から図１６を参照しながら、以下に詳細に説明する。 <Switch operation>
The operation of the switch 1 according to the embodiment of the present invention will be described below in detail with reference to FIGS. 4 and 15 to 16.
　スイッチ１は、レバー３０が外部から押圧されない場合には、図４に示すように、可動コンタクト１００ａが固定コンタクト８１の固定接点８７及び固定コンタクト８３の固定接点８７と接続していると共に、可動コンタクト１００ｂが固定コンタクト８４の固定接点８７及び固定コンタクト８６の固定接点８７と接続している初期状態になっている。 When the lever 30 is not pressed from the outside, the switch 1 has the movable contact 100a connected to the fixed contact 87 of the fixed contact 81 and the fixed contact 87 of the fixed contact 83 as shown in FIG. In the initial state, 100b is connected to the fixed contact 87 of the fixed contact 84 and the fixed contact 87 of the fixed contact 86.
　スイッチ１は、初期状態においてばね４０の付勢力に抗してレバー３０が下方に押圧された場合に、図１５に示すように、ラバー３５が弾性変形し、ばね４０が収縮すると共に、フック５０が下方に移動することに伴ってフック５０の係止部５３に係止されているばね７０が伸長する。また、アクチュエータ６０は、支点部２３１に当接している回動部６４を回転中心として、図１５において反時計回りに回動する。更に、スライダー９０は、アクチュエータ６０の係合部６３によって右側の係合突出部９３が右方に押圧されることにより、右方にスライドを開始する。図１５の状態の場合には、ばね７０の係止部７１とアクチュエータ６０の係止孔６１１との係止部Ｑと、ばね７０の係止部７２が係止しているフック５０の係止部５３と、を結ぶ仮想の直線Ｌ１は、係止部Ｑよりも右方において、係止部Ｑとアクチュエータ６０が回動する際の支点となる回動部６４とを結ぶ仮想の直線Ｌ２よりも上方にある。従って、アクチュエータ６０は、先端部６１が回動部６４よりも上方に位置している状態を維持する。 In the switch 1, in the initial state, when the lever 30 is pressed downward against the urging force of the spring 40, the rubber 35 elastically deforms, the spring 40 contracts, and the hook 50 as shown in FIG. The spring 70 locked to the locking portion 53 of the hook 50 expands as the arrow moves downward. Further, the actuator 60 rotates counterclockwise in FIG. 15 about the rotation portion 64 that is in contact with the fulcrum portion 231 as the rotation center. Further, the slider 90 starts sliding to the right when the right engaging protrusion 93 is pressed to the right by the engaging portion 63 of the actuator 60. In the case of the state shown in FIG. 15, the engagement portion Q of the engagement portion 71 of the spring 70 and the engagement hole 611 of the actuator 60 and the engagement of the hook 50 in which the engagement portion 72 of the spring 70 is engaged. An imaginary straight line L1 connecting the portion 53 with the imaginary straight line L2 connecting the engaging portion Q and the rotating portion 64 serving as a fulcrum when the actuator 60 rotates to the right of the engaging portion Q. Is also above. Therefore, the actuator 60 maintains the state in which the tip portion 61 is located above the rotating portion 64.
　次に、レバー３０が更に下方に押圧されて、図１６に示すように、仮想の直線Ｌ１が係止部Ｑの右方において仮想の直線Ｌ２よりも下方になった際に、ばね７０が収縮することによりアクチュエータ６０が瞬時に傾斜面２３ａから離れて傾斜面１４ａに当接する。また、スライダー９０は、アクチュエータ６０の係合部６３によって右側の係合突出部９３が瞬時に右方に押圧されることにより、可動コンタクト１００ａが固定接点８７上を右方にスライドしながら、固定コンタクト８１の固定接点８７及び固定コンタクト８２の固定接点８７と瞬時に接続すると共に、可動コンタクト１００ｂが固定接点８７上を右方にスライドしながら、固定コンタクト８４の固定接点８７及び固定コンタクト８５の固定接点８７と瞬時に接続する。 Next, when the lever 30 is further pressed downward and the imaginary straight line L1 becomes lower than the imaginary straight line L2 on the right side of the locking portion Q as shown in FIG. 16, the spring 70 contracts. By doing so, the actuator 60 instantly separates from the inclined surface 23a and comes into contact with the inclined surface 14a. Further, the slider 90 is fixed while the movable contact 100a slides right on the fixed contact 87 by the right engagement protrusion 93 being instantaneously pressed right by the engagement portion 63 of the actuator 60. The fixed contact 87 of the fixed contact 84 and the fixed contact 87 of the fixed contact 82 are instantaneously connected, and the fixed contact 87 of the fixed contact 84 and the fixed contact 85 are fixed while the movable contact 100b slides rightward on the fixed contact 87. Instantly connect to contact 87.
　これにより、可動コンタクト１００ａと固定コンタクト群８０ａとがセルフクリーニングを行うことができると共に、可動コンタクト１００ｂと固定コンタクト群８０ｂとがセルフクリーニングを行うことができるため、可動コンタクト１００ａと固定コンタクト群８０ａとの間に異物が挟まらないようにすることができると共に、可動コンタクト１００ｂと固定コンタクト群８０ｂとの間に異物が挟まらないようにすることができ、接触信頼性を向上させることができる。 As a result, the movable contact 100a and the fixed contact group 80a can be self-cleaned, and the movable contact 100b and the fixed contact group 80b can be self-cleaned, so that the movable contact 100a and the fixed contact group 80a are It is possible to prevent foreign matter from being caught between the movable contacts 100b and the fixed contact group 80b, and it is possible to improve contact reliability.
　次に、レバー３０の下方への押圧力を解除した場合には、ラバー３５の弾性復帰力によりラバー３５が元の状態に戻ろうとし、ばね４０の付勢力によってレバー３０が上方に移動すると共に、フック５０によってばね７０が伸長してアクチュエータ６０が図１６において時計回りに回動する。この際に、ばね４０によってレバー３０をカバー２０から外部に突出する方向に付勢することにより、レバー３０を容易に復帰させることができる。また、ラバー３５の弾性復帰力によってレバー３０をカバー２０から外部に突出する方向に押圧することができ、レバー３０を更に容易に復帰させることができる。 Next, when the downward pressing force of the lever 30 is released, the elastic return force of the rubber 35 tries to return the rubber 35 to the original state, and the biasing force of the spring 40 moves the lever 30 upward. , The spring 70 is extended by the hook 50, and the actuator 60 is rotated clockwise in FIG. At this time, the spring 30 urges the lever 30 in the direction of protruding from the cover 20 to the outside, so that the lever 30 can be easily returned. In addition, the elastic return force of the rubber 35 can press the lever 30 in the direction of protruding from the cover 20, and the lever 30 can be returned more easily.
　次に、レバー３０がばね４０の付勢力によって更に上方へ復帰して、仮想の直線Ｌ１が係止部Ｑよりも右方において仮想の直線Ｌ２よりも上方になった際に、ばね７０が収縮することによりアクチュエータ６０が瞬時に傾斜面１４ａから離れて傾斜面２３ａに当接する。これにより、スライダー９０は、アクチュエータ６０の係合部６３によって左側の係合突出部９３が瞬時に左方に押圧されることにより、可動コンタクト１００ａが固定コンタクト８１の固定接点８７及び固定コンタクト８３の固定接点８７と瞬時に接続すると共に、可動コンタクト１００ｂが固定コンタクト８４の固定接点８７及び固定コンタクト８６の固定接点８７と瞬時に接続して、図４に示す初期状態に戻る。 Next, when the lever 30 returns further upward by the urging force of the spring 40 and the virtual straight line L1 is above the virtual straight line L2 to the right of the locking portion Q, the spring 70 contracts. By doing so, the actuator 60 instantly separates from the inclined surface 14a and contacts the inclined surface 23a. As a result, in the slider 90, the movable contact 100 a is fixed to the fixed contact 87 of the fixed contact 81 and the fixed contact 83 by the engagement portion 63 of the actuator 60 instantaneously pressing the left engagement protrusion 93 to the left. While being instantly connected to the fixed contact 87, the movable contact 100b is instantly connected to the fixed contact 87 of the fixed contact 84 and the fixed contact 87 of the fixed contact 86 to return to the initial state shown in FIG.
　このように、レバー３０の上下方向の移動動作は、アクチュエータ６０の回転動作に変換された後に、スライダー９０の左右方向のスライド動作に変換される。これにより、スライダー９０は、レバー３０の移動方向である上下方向と異なる左右方向に移動すると共に、アクチュエータ６０の回転動作と異なるスライド動作を行う。 In this way, the vertical movement movement of the lever 30 is converted into the rotation movement of the actuator 60 and then converted into the horizontal movement movement of the slider 90. As a result, the slider 90 moves in the left-right direction, which is different from the up-down direction, which is the moving direction of the lever 30, and performs a sliding operation different from the rotating operation of the actuator 60.
　上記の動作を行うスイッチ１は、固定接点８７と接続する可動コンタクト１００ａ及び可動コンタクト１００ｂの可動接点１０１を下方に凸となる湾曲形状にすることにより、可動接点１０１が固定接点８７上をスライドしながら接続する場合であっても、固定接点８７及び可動接点１０１の摩耗を抑制することができると共に、固定接点８７及び可動接点１０１の摩耗によるスイッチ１の内部における異物の発生を抑制することができる。 In the switch 1 that performs the above operation, the movable contact 101a of the movable contact 100a and the movable contact 100b connected to the fixed contact 87 has a curved shape that is convex downward, so that the movable contact 101 slides on the fixed contact 87. Even when the connection is made, the wear of the fixed contact 87 and the movable contact 101 can be suppressed, and the generation of foreign matter inside the switch 1 due to the wear of the fixed contact 87 and the movable contact 101 can be suppressed. .
