そして従来、さらなるスイッチの薄型化（レバー部（４）の揺動軸に沿う方向の厚み寸法の薄型化）が求められているが、その場合、旋動体（５）の外径寸法を小さくしなければならず、それに伴ってロッド（７）及び圧縮バネ（６）の外径寸法も小さくしなければならない。しかしながらロッド（７）及び圧縮バネ（６）の外径寸法の小型化にはその強度や耐久性や弾発力の維持の点から限界があり、このため更なる厚みの薄型化が図れなかった。 Conventionally, there has been a demand for further thinning of the switch (thinning of the thickness in the direction along the swing axis of the lever (4)). In that case, the outer diameter of the rotating body (5) is reduced. Accordingly, the outer diameter of the rod (7) and the compression spring (6) must be reduced accordingly. However, there is a limit to the reduction of the outer diameter of the rod (7) and the compression spring (6) from the standpoint of maintaining the strength, durability, and elasticity, and therefore the thickness cannot be further reduced. .

Since the bullet body 181 is a substantially rectangular flat plate, the thickness in the direction along the swing axis K1 (axis of the shaft portion 177) of the operation knob 150 in the cross section thereof is perpendicular to the swing axis K1. It is formed thinner than the thickness. The shape and dimensions of the elastic body 181 are accommodated in the elastic member storage part 175 of the knob body 170 so as to be movable up and down (slidably moved), that is, the shape of the cross section thereof is the cross section of the elastic member storage part 175. It is formed in substantially the same shape as Further, the lower part of the elastic body 181 projects in a tapered shape, and the front end surface (lower end surface) thereof is an elastic contact surface 183 formed in a substantially arc surface shape. On the other hand, a spring accommodating portion 185 is formed on the upper side of the elastic body 181. The spring accommodating portion 185 is cut out so that both sides of the thinly formed side (both sides having a flat shape) are released. The depth dimension of the spring accommodating portion 185 is formed smaller than the length dimension of the elastic spring 187. Further, the thickness dimension of the thin side of the elastic body 181 is formed to be the same as the outer diameter dimension of the elastic spring 187 or slightly larger than the outer diameter dimension of the elastic spring 187. The material of the projectile 181 is not limited to synthetic resin, and may be formed of metal (aluminum, brass, etc.), for example.

次にこのスイッチ１−１を組み立てるには、まず短絡片２００の取付基部２０１を可動接点体支持体５０の支持体本体部５１上に載置する。このとき支持体本体部５１の短絡片取付部６１を短絡片２００の取付部２０７に挿入し、同時に弾接部２０５を開口５８内に挿入してストッパ部当接部２１１をストッパ部５９に弾接させる。そして少なくとも一方の短絡片取付部６１の先端をかしめて潰し、これによって短絡片２００を可動接点体支持体５０上に取り付ける。次にケース１０の各接点収納部１１内にそれぞれ１組ずつの短絡片２００を取り付けた可動接点体支持体５０と固定接点体４０とを挿入し、固定接点体４０の端子４３と可動接点体支持体５０の端子５３とを、ケース１０の各端子挿入孔１５に挿入する。そしてケース１０の底面から突出する各端子４３，５３の根元の固定部４７，５７を機械的に潰し、これによって各固定接点体４０と可動接点体支持体５０をケース１０内の底面に固定する。さらに図示はしていないが、ケース１０の下面の前記各端子挿入孔１５の周囲にエポキシ系接着剤などからなる封止樹脂を充填し、端子４３，５３と端子挿入孔１５との間にあるわずかな隙間を封止する。 Next, in order to assemble the switch 1-1, first, the mounting base 201 of the short-circuit piece 200 is placed on the support body 51 of the movable contact body support 50. At this time, the short-circuit piece attaching portion 61 of the support body 51 is inserted into the attachment portion 207 of the short-circuit piece 200, and at the same time, the elastic contact portion 205 is inserted into the opening 58 and the stopper contact portion 211 is elastically attached to the stopper portion 59. Make contact. Then, the tip of at least one of the short-circuit piece mounting portions 61 is caulked and crushed, thereby attaching the short-circuit piece 200 onto the movable contact body support 50. Next, the movable contact body support body 50 and the fixed contact body 40 each having a pair of short-circuit pieces 200 mounted therein are inserted into the contact storage portions 11 of the case 10, and the terminal 43 and the movable contact body of the fixed contact body 40 are inserted. The terminals 53 of the support body 50 are inserted into the terminal insertion holes 15 of the case 10. Then, the fixed portions 47 and 57 at the bases of the terminals 43 and 53 protruding from the bottom surface of the case 10 are mechanically crushed, thereby fixing each fixed contact body 40 and the movable contact body support body 50 to the bottom surface in the case 10. . Although not shown in the drawing, a sealing resin made of an epoxy-based adhesive or the like is filled around each terminal insertion hole 15 on the lower surface of the case 10, and is located between the terminals 43 and 53 and the terminal insertion hole 15. Seal small gaps.

次にケース１０の各接点収納部１１内に一対の可動接点体７０を収納し、その際可動接点体７０の係止部７３に可動接点体支持体５０の可動接点体係止部５６を係止し、同時に可動接点体７０の当接部分７５を可動接点体支持体５０の上辺５５に線状に当接させる。可動接点体７０は当接部分７５を上辺５５に当接した状態のままこの当接部分７５を中心に揺動自在となる。次にカバー８０をケース１０上に載置し、ケース１０の上面の開口を塞ぐ。 Next, a pair of movable contact bodies 70 is housed in each contact housing portion 11 of the case 10, and at that time, the movable contact body locking portion 56 of the movable contact body support 50 is engaged with the locking portion 73 of the movable contact body 70. At the same time, the contact portion 75 of the movable contact body 70 is linearly contacted with the upper side 55 of the movable contact body support 50. The movable contact body 70 can swing around the contact portion 75 while the contact portion 75 is in contact with the upper side 55. Next, the cover 80 is placed on the case 10 to close the opening on the upper surface of the case 10.

次につまみ外装体１６０下面の凹部内に、つまみ本体１７０の上面側を収納し、その際つまみ外装体１６０の各本体取付部１６３をつまみ本体１７０の各外装体取付部１７１に挿入し、つまみ本体１７０の下面に突出する各本体取付部１６３の先端を熱かしめによって潰し、つまみ外装体１６０とつまみ本体１７０とを一体化する。そしてつまみ本体１７０の一対の弾発部材収納部１７５に弾発部材１８０を収納し、さらにこの操作つまみ１５０を外側ケース１００の操作つまみ収納部１０５に収納し、その際つまみ本体１７０に設けた軸部１７７を外側ケース１００に設けた軸支孔１０９に挿入し、これによって操作つまみ１５０を外側ケース１００に対して揺動自在に軸支する。 Next, the upper surface side of the knob main body 170 is housed in the recess on the lower surface of the knob outer body 160, and each main body attachment portion 163 of the knob outer body 160 is inserted into each outer body attachment portion 171 of the knob main body 170. The tip of each main body mounting portion 163 protruding from the lower surface of the main body 170 is crushed by heat caulking, and the knob exterior body 160 and the knob main body 170 are integrated. The elastic member 180 is stored in the pair of elastic member storage portions 175 of the knob body 170, and the operation knob 150 is further stored in the operation knob storage portion 105 of the outer case 100. The portion 177 is inserted into a shaft support hole 109 provided in the outer case 100, whereby the operation knob 150 is pivotally supported with respect to the outer case 100.

そしてこの外側ケース１００を前記カバー８０の上に載置する。このとき操作つまみ１５０の操作体１９０はカバー８０の操作体挿通孔８３を貫通し、先端の一対の弾発体１８１の弾接面１８３はそれぞれ各可動接点体７０の上面に弾接する。同時に外側ケース１００の各取付突起１１５をケース１０の各取付部１９に挿入し、各取付突起１１５の先端をケース１０の下面で熱かしめし、これによってケース１０に外側ケース１００を固定する。これによってスイッチ１−１の組み立てが完了する。なお上記組立手順はその一例であり、他の各種異なる組立手順を用いて組み立てても良いことはいうまでもない。 Then, the outer case 100 is placed on the cover 80. At this time, the operation body 190 of the operation knob 150 passes through the operation body insertion hole 83 of the cover 80, and the elastic contact surfaces 183 of the pair of elastic bodies 181 at the distal ends are in elastic contact with the upper surfaces of the movable contact bodies 70, respectively. At the same time, the mounting protrusions 115 of the outer case 100 are inserted into the mounting portions 19 of the case 10, and the tips of the mounting protrusions 115 are heat caulked on the lower surface of the case 10, thereby fixing the outer case 100 to the case 10. This completes the assembly of the switch 1-1. The above assembling procedure is an example, and it goes without saying that the assembly may be performed using other various assembling procedures.

以上のようにして構成されたスイッチ１−１は、図３に示すように、内部に接点収納部１１を有するケース１０と、ケース１０の接点収納部１１の底面に設置される少なくとも一対の固定接点体４０及び可動接点体支持体５０と、可動接点体支持体５０に揺動自在に軸支され、固定接点体４０に設けた固定接点４５に接離する可動接点７１を有する可動接点体７０と、可動接点体７０の上部に設置され、可動接点体７０の上面に当接しながら移動することで可動接点体７０を揺動操作する操作体１９０を有する操作つまみ１５０とを具備し、さらに操作体１９０は、操作つまみ１５０に設けた弾発部材収納部１７５内に、弾発バネ１８７と、この弾発バネ１８７によって弾発される弾発体１８１とを収納して構成され、少なくとも弾発部材収納部１７５内での弾発体１８１の横断面における操作つまみ１５０の揺動軸Ｋ１に沿う方向の厚みを、揺動軸Ｋ１に直交する方向の厚みよりも薄く形成して構成されている。 As shown in FIG. 3, the switch 1-1 configured as described above includes a case 10 having a contact housing portion 11 therein and at least a pair of fixed members installed on the bottom surface of the contact housing portion 11 of the case 10. A movable contact body 70 having a contact body 40, a movable contact body support body 50, and a movable contact body 71 pivotally supported by the movable contact body support body 50 so as to be in contact with and separated from a fixed contact 45 provided on the fixed contact body 40. And an operation knob 150 having an operation body 190 that swings the movable contact body 70 by moving while abutting on the upper surface of the movable contact body 70. The body 190 is configured by housing a resilient spring 187 and a resilient body 181 ejected by the resilient spring 187 in a resilient member housing 175 provided on the operation knob 150, and at least the resilient body. Material collection The direction of the thickness along the pivot shaft K1 of the operation knob 150 in the cross section of the bullet inducer 181 at parts within 175, is configured by thinner than the direction of thickness perpendicular to the swing axis K1.

図３，図４は操作つまみ１５０が一方の側に揺動しきってスイッチがオフして安定している状態を示している。同図に示す状態は、操作つまみ１５０の操作体１９０の弾発体１８１の弾接面１８３が可動接点体７０の上辺５５に当接している当接部分７５から見て可動接点７１とは反対側の上面を弾接している状態を示しており、これによって可動接点体７０はその当接部７７が可動接点体支持体５０の支持体本体部５１上に当接し、従って可動接点７１は固定接点体４０の固定接点４５から離れ、固定接点体４０と可動接点体支持体５０間、つまり両端子４３，５３間はオフ状態となっている。またこのとき、短絡片２００のアーム部２０３はその先端のストッパ部当接部２１１が可動接点体支持体５０のストッパ部５９に弾接しているので、その位置よりも上方には移動せず、従って弾接部２０５は可動接点体７０の下面から少し離間している。 3 and 4 show a state where the operation knob 150 is fully swung to one side and the switch is turned off to be stable. The state shown in the figure is opposite to the movable contact 71 when viewed from the contact portion 75 where the elastic contact surface 183 of the elastic body 181 of the operation body 190 of the operation knob 150 is in contact with the upper side 55 of the movable contact body 70. In this state, the upper surface of the movable contact body 70 is elastically contacted, so that the contact portion 77 of the movable contact body 70 abuts on the support body portion 51 of the movable contact body support body 50, and thus the movable contact 71 is fixed. The contact body 40 is separated from the fixed contact 45, and between the fixed contact body 40 and the movable contact body support body 50, that is, between the terminals 43 and 53 is in an OFF state. At this time, the arm portion 203 of the short-circuit piece 200 does not move upward from the position because the stopper portion abutting portion 211 at the tip thereof is in elastic contact with the stopper portion 59 of the movable contact body support 50. Therefore, the elastic contact portion 205 is slightly separated from the lower surface of the movable contact body 70.

次に前記操作つまみ１５０の上方向に持ち上がっている側の上面を押し込む方向に（図３に示す矢印Ｂ方向に）押圧すると、弾発体１８１の弾接面１８３が可動接点体７０の上面を可動接点７１側に向けて移動（摺動）を始め、可動接点体７０の当接部分７５の部分に至るまでは弾発バネ１８７が押し縮められて弾発体１８１は弾発部材収納部１７５内に押し込められ、弾発面１８３が当接部分７５の部分を通過した際に可動接点体７０は当接部分７５の部分を揺動軸として可動接点７１側が下降するように揺動を始め、押し縮められていた弾発バネ１８７の弾発力によって可動接点体７０は急速に揺動して図１０に示すように瞬時に可動接点７１が固定接点体４０の固定接点４５に当接し、固定接点体４０と可動接点体支持体５０間、つまり両端子４３，５３間がオンする。このとき操作つまみ１５０は他方の側に揺動しきって安定する。 Next, when the upper surface of the operation knob 150 lifted upward is pressed in the direction of pushing in (in the direction of arrow B shown in FIG. 3), the elastic contact surface 183 of the elastic body 181 depresses the upper surface of the movable contact body 70. The elastic spring 187 is pushed and shrunk until it starts moving (sliding) toward the movable contact 71 and reaches the contact portion 75 of the movable contact 70, and the elastic 181 is stored in the elastic member housing 175. When the resilient contact surface 183 passes through the portion of the contact portion 75, the movable contact body 70 starts swinging so that the movable contact 71 side descends with the contact portion 75 as the swing axis. The movable contact body 70 swings rapidly due to the elastic force of the elastic spring 187 that has been compressed, and the movable contact 71 abuts against the fixed contact 45 of the fixed contact body 40 as shown in FIG. Between the contact body 40 and the movable contact body support body 50, Between the two terminals 43 and 53 is turned on. At this time, the operation knob 150 swings to the other side and becomes stable.

そして上述のように可動接点７１側が下降している途中において、短絡片２００の弾接部２０５が可動接点体７０の下面に当接し、可動接点体７０が揺動し切るまで弾接部２０５は可動接点体７０の下面によって押し下げられる。つまり可動接点７１が固定接点４５にオンするその前後においては、短絡片２００の弾接部２０５が可動接点体７０に常に弾接するので、たとえスイッチ１−１がオンする際に可動接点体７０が立設部５４の上辺５５上でバウンシングしても、可動接点体７０と可動接点体支持体５０間は確実に電気的に接続された状態を維持する。 As described above, the elastic contact portion 205 of the short-circuit piece 200 is in contact with the lower surface of the movable contact body 70 while the movable contact 71 side is being lowered, and the elastic contact portion 205 is not swung until the movable contact body 70 is completely swung. It is pushed down by the lower surface of the movable contact body 70. That is, before and after the movable contact 71 is turned on to the fixed contact 45, the elastic contact portion 205 of the short-circuit piece 200 is always in elastic contact with the movable contact body 70, so that even when the switch 1-1 is turned on, the movable contact body 70 is Even when bouncing on the upper side 55 of the standing portion 54, the movable contact body 70 and the movable contact body support body 50 are reliably maintained in an electrically connected state.

そしてこのスイッチ１−１においては、前述のように、弾発体１８１の厚み（特に弾発部材収納部１７５内での厚み）を薄く構成したので、操作つまみ１５０の揺動軸Ｋ１に沿う方向のスイッチ１―１全体の厚み寸法を容易に薄くすることができる。なおその際、弾発体１８１の揺動軸Ｋ１に直交する方向の厚み寸法を大きくすることなどによって、弾発体１８１の強度はこれを容易に強く維持しておくことができる。 In the switch 1-1, as described above, since the thickness of the bullet member 181 (particularly, the thickness in the bullet member storage portion 175) is thin, the direction along the swing axis K1 of the operation knob 150 is provided. The thickness of the entire switch 1-1 can be easily reduced. At this time, by increasing the thickness dimension of the bullet 181 in the direction orthogonal to the swing axis K1, the strength of the bullet 181 can be easily maintained.

特にこのスイッチ１−１のようにバネ収納部１８５を切り欠きで構成した場合は、弾発体１８１の厚み寸法を弾発バネ１８７の直径寸法と同じ程度まで薄くできるので、より効果的にスイッチ１−１の厚み寸法の薄型化が図れる。言い換えれば、弾発バネ１８７の直径を小さくすることなく、すなわちその耐久性や弾発力を小さくすることなくスイッチ１−１の薄型化が図れる。 In particular, when the spring accommodating portion 185 is configured with a notch like the switch 1-1, the thickness dimension of the elastic body 181 can be reduced to the same extent as the diameter dimension of the elastic spring 187. The thickness of 1-1 can be reduced. In other words, the switch 1-1 can be thinned without reducing the diameter of the elastic spring 187, that is, without reducing its durability and elastic force.

またこのスイッチ１−１においては、ケース１０と外側ケース１００間の固定を、これらの外周側面の内の揺動軸Ｋ１に垂直な側の外周側面ではなく、揺動軸Ｋ１に沿う方向の外周側面において行っているので、このことによってもスイッチ１−１の揺動軸Ｋ１に沿う方向の厚み寸法の薄型化が図れる。 Further, in this switch 1-1, the case 10 and the outer case 100 are fixed not on the outer peripheral side surface of the outer peripheral side surface perpendicular to the swing axis K1, but on the outer periphery in the direction along the swing axis K1. Since this is performed on the side surface, the thickness of the switch 1-1 in the direction along the swing axis K1 can be reduced.

図１１は本発明の第２実施形態に係るスイッチ１−２の概略断面図（図３に相当する部分での断面図）、図１２はスイッチ１−２の概略断面図（図４に相当する部分での断面図）、図１３はスイッチ１−２を上側から見た上側部品の分解斜視図（図５に相当する分解斜視図）である。このスイッチ１−２において、前記図１〜図１０に示すスイッチ１−１と同一又は相当部分には同一符号を付す。なお以下で説明する事項以外の事項については、前記図１〜図１０に示すスイッチ１−１と同じである。 11 is a schematic cross-sectional view of the switch 1-2 according to the second embodiment of the present invention (a cross-sectional view of a portion corresponding to FIG. 3), and FIG. 12 is a schematic cross-sectional view of the switch 1-2 (corresponding to FIG. 4). FIG. 13 is an exploded perspective view (an exploded perspective view corresponding to FIG. 5) of the upper part when the switch 1-2 is viewed from above. In this switch 1-2, the same or corresponding parts as those in the switch 1-1 shown in FIGS. Items other than those described below are the same as those of the switch 1-1 shown in FIGS.

このスイッチ１−２において前記スイッチ１−１と相違する点は、つまみ本体１７０と弾発体１８１の構造である。即ちスイッチ１−２に用いるつまみ本体１７０においては、２つに分かれた操作体本体部１７３の先端部分のそれぞれの両側面（寸法の長い側の両側面）の下辺に凹部からなる弾発体挿入部１７４を設けている。弾発体挿入部１７４は下記する弾発体１８１の一対の軸支部３０５の上側部分をぴったり挿入する形状に形成されている。その他の部分の構成はスイッチ１−１のつまみ本体１７０と同一なので、その説明は省略する。 The switch 1-2 is different from the switch 1-1 in the structure of the knob body 170 and the projectile 181. That is, in the knob main body 170 used for the switch 1-2, the projectile is inserted into the lower end of each of the two end surfaces of the operation body main body 173 divided into two parts (both side surfaces on the longer dimension side). A portion 174 is provided. The projectile insertion portion 174 is formed in a shape that allows the upper portions of a pair of shaft support portions 305 of the projectile 181 described below to be inserted exactly. Since the configuration of the other parts is the same as that of the knob body 170 of the switch 1-1, description thereof is omitted.

スイッチ１−２に用いる弾発体１８１は、弾発体本体部３００と回転体３５０とを具備して構成されている。弾発体本体部３００は略長方形平板状のスライド部３０１の下部に回転体取付部３０３を一体成形にて形成して構成されている。スライド部３０１には前記スイッチ１−１の場合と同様に、その横断面における操作つまみ１５０の揺動軸Ｋ１（軸部１７７の軸）に沿う方向の厚みを、この揺動軸Ｋ１に直交する方向の厚みよりも薄く形成している。このスライド部３０１はつまみ本体１７０の弾発部材収納部１７５内に上下動（スライド移動）自在に収納される形状・寸法、つまりその横断面の形状が弾発部材収納部１７５の横断面の形状とほぼ同一形状に形成されている。スライド部３０１の上辺には弾発バネ１８７を挿入する切り欠きからなる（溝からなる）バネ収納部３０２が形成されている。バネ収納部３０２は薄く形成された側の両面（平面状となっている両面）が解放されるように切り欠かれている。バネ収納部３０２の深さ寸法は、弾発バネ１８７の長さ寸法よりも小さく形成されている。またスライド部３０１の薄い側の厚み寸法は、弾発バネ１８７の外径寸法と同一、又は弾発バネ１８７の外径寸法よりも少し大きい寸法に形成されている。一方回転体取付部３０３は、一対の平板状の軸支部３０５の間にスリット状の回転体収納部３０７を形成して構成されている。各軸支部３０５の下端部中央の対向する位置には円形凹状の軸受部３０９が形成されている。回転体取付部３０３の揺動軸Ｋ１に沿う方向の厚み寸法は、つまみ本体１７０の操作体本体部１７３の２つに分かれた先端側の部分の揺動軸Ｋ１に沿う方向の厚み寸法と同一またはそれより小さい寸法に形成されている。なお弾発体本体部３００の材質は合成樹脂に限られず、例えば金属（アルミニウムや黄銅等）等で形成しても良い。 The bullet body 181 used for the switch 1-2 is configured to include a bullet body body 300 and a rotating body 350. The bullet body main body 300 is formed by integrally forming a rotating body mounting portion 303 below a slide portion 301 having a substantially rectangular flat plate shape. As in the case of the switch 1-1, the slide portion 301 has a thickness in the direction along the swing axis K1 (axis of the shaft portion 177) of the operation knob 150 in the cross section thereof orthogonal to the swing axis K1. It is formed thinner than the thickness in the direction. The shape and dimensions of the slide portion 301 are accommodated in the elastic member storage portion 175 of the knob body 170 so as to be movable up and down (slidably moved), that is, the shape of the cross section is the shape of the cross section of the elastic member storage portion 175. Are formed in almost the same shape. On the upper side of the slide portion 301, a spring accommodating portion 302 made of a notch (made of a groove) into which the elastic spring 187 is inserted is formed. The spring accommodating portion 302 is cut out so that both sides of the thinly formed side (both sides that are flat) are released. The depth dimension of the spring accommodating portion 302 is formed smaller than the length dimension of the elastic spring 187. Further, the thickness dimension on the thin side of the slide portion 301 is formed to be the same as the outer diameter dimension of the spring spring 187 or slightly larger than the outer diameter dimension of the spring spring 187. On the other hand, the rotating body mounting portion 303 is configured by forming a slit-shaped rotating body storage portion 307 between a pair of flat plate-like shaft support portions 305. A circular concave bearing portion 309 is formed at an opposing position in the center of the lower end portion of each shaft support portion 305. The thickness dimension in the direction along the rocking axis K1 of the rotating body mounting portion 303 is the same as the thickness dimension in the direction along the rocking axis K1 of the portion on the distal end side of the operation body main body portion 173 of the knob body 170. Or smaller dimensions. The material of the bullet body main body 300 is not limited to synthetic resin, and may be formed of metal (aluminum, brass, etc.), for example.

回転体３５０は金属製（たとえばアルミニウム製）であり、円板状の本体部３５１の両側面の中心位置から一対の回転軸３５３を突出して構成されている。回転体３５０の揺動軸Ｋ１に沿う方向の厚み寸法、即ち両回転軸３５３の両端面間の距離は、つまみ本体１７０の操作体本体部１７３の２つに分かれた先端側の部分の揺動軸Ｋ１に沿う方向の厚み寸法と同一またはそれより小さい寸法に形成されている。回転体３５０の材質は合成樹脂などの他の材質でも良い。 The rotating body 350 is made of metal (for example, aluminum), and is configured to project a pair of rotating shafts 353 from the center positions on both side surfaces of the disk-shaped main body 351. The thickness dimension in the direction along the swing axis K1 of the rotating body 350, that is, the distance between both end surfaces of the both rotating shafts 353 is the swing of the tip side portion of the control body main body 173 of the knob body 170. The dimension is the same as or smaller than the thickness dimension in the direction along the axis K1. The material of the rotating body 350 may be another material such as a synthetic resin.

そして操作つまみ１５０の組み立ては、まず前記スイッチ１−１の場合と同様に、つまみ外装体１６０下面の凹部内に、つまみ本体１７０の上面側を収納し、その際つまみ外装体１６０の各本体取付部１６３をつまみ本体１７０の各外装体取付部１７１に挿入し、つまみ本体１７０の下面に突出する各本体取付部１６３の先端を熱かしめによって潰し、つまみ外装体１６０とつまみ本体１７０とを一体化する。一方弾発体本体部３００の回転体収納部３０７内に回転体３５０の本体部３５１を挿入し、その際回転体３５０の一対の回転軸３５３を弾発体本体部３００の軸受部３０９にスナップイン係合によって回転自在に係合する。そしてつまみ本体１７０の一対の弾発部材収納部１７５に、弾発体本体部３００のバネ収納部３０２に弾発バネ１８７を収納してなる弾発部材１８０のスライド部３０１の部分を上下動自在に収納する。これによって操作つまみ１５０の組み立てが完了する。なおその他のスイッチ１−２全体の組み立て方法は、前記スイッチ１−１で説明した組み立て方法と同一なので、その説明は省略する。 As for the assembly of the operation knob 150, first, similarly to the case of the switch 1-1, the upper surface side of the knob body 170 is housed in the recess on the lower surface of the knob exterior body 160. The part 163 is inserted into each exterior body attachment part 171 of the knob body 170, and the tip of each body attachment part 163 protruding from the lower surface of the knob body 170 is crushed by heat caulking, so that the knob exterior body 160 and the knob body 170 are integrated. To do. On the other hand, the main body portion 351 of the rotating body 350 is inserted into the rotating body housing portion 307 of the projectile body main body 300, and at this time, the pair of rotating shafts 353 of the rotating body 350 are snapped to the bearing portion 309 of the projectile body main body 300. It engages rotatably by in-engagement. The pair of elastic member storage portions 175 of the knob main body 170 and the portion of the slide portion 301 of the elastic member 180 in which the elastic spring 187 is stored in the spring storage portion 302 of the elastic body main body 300 are freely movable up and down. Store in. Thereby, the assembly of the operation knob 150 is completed. In addition, since the assembly method of the other switch 1-2 whole is the same as the assembly method demonstrated with the said switch 1-1, the description is abbreviate | omitted.

以上のようにして構成されたスイッチ１−２は、図１１，図１２に示すように、内部に接点収納部１１を有するケース１０と、ケース１０の接点収納部１１の底面に設置される少なくとも一対の固定接点体４０及び可動接点体支持体５０と、可動接点体支持体５０に揺動自在に軸支され、固定接点体４０に設けた固定接点４５に接離する可動接点７１を有する可動接点体７０と、可動接点体７０の上部に設置され、可動接点体７０の上面に当接しながら移動することで可動接点体７０を揺動操作する操作体１９０を有する操作つまみ１５０とを具備し、さらに操作体１９０は、操作つまみ１５０に設けた弾発部材収納部１７５内に、弾発バネ１８７と、この弾発バネ１８７によって弾発される弾発体１８１とを収納して構成され、少なくとも弾発部材収納部１７５内での弾発体１８１の横断面（即ちスライド部３０１の横断面）における操作つまみ１５０の揺動軸Ｋ１に沿う方向の厚みを、揺動軸Ｋ１に直交する方向の厚みよりも薄く形成して構成されている。 As shown in FIGS. 11 and 12, the switch 1-2 configured as described above includes at least a case 10 having a contact housing portion 11 therein and a bottom surface of the contact housing portion 11 of the case 10. A pair of fixed contact body 40 and a movable contact body support body 50, and a movable contact 71 that is pivotally supported by the movable contact body support body 50 so as to be swingable and contact and separate from a fixed contact 45 provided on the fixed contact body 40. A contact body 70 and an operation knob 150 that is installed on the upper side of the movable contact body 70 and has an operation body 190 that swings the movable contact body 70 by moving while contacting the upper surface of the movable contact body 70 are provided. Further, the operating body 190 is configured by storing a spring spring 187 and a spring body 181 which is springed by the spring spring 187 in a spring member storage portion 175 provided on the operation knob 150. at least The thickness in the direction along the swing axis K1 of the operation knob 150 in the transverse section of the projectile member 181 (that is, the transverse section of the slide portion 301) in the firing member storage section 175 is the thickness in the direction perpendicular to the swing axis K1. It is formed to be thinner.

図１１，図１２は操作つまみ１５０が一方の側に揺動しきってスイッチがオフして安定している状態を示している。同図に示す状態は、操作つまみ１５０の操作体１９０の回転体３５０外周面の弾接面１８３が可動接点体７０の上辺５５に当接している当接部分７５から見て可動接点７１とは反対側の上面を弾接している状態を示しており、これによって可動接点体７０はその当接部７７が可動接点体支持体５０の支持体本体部５１上に当接し、従って可動接点７１は固定接点体４０の固定接点４５から離れ、固定接点体４０と可動接点体支持体５０間、つまり両端子４３，５３間はオフ状態となっている。またこのとき、短絡片２００のアーム部２０３はその先端のストッパ部当接部２１１が可動接点体支持体５０のストッパ部５９に弾接しているので、その位置よりも上方には移動せず、従って弾接部２０５は可動接点体７０の下面から少し離間している。 11 and 12 show a state where the operation knob 150 is fully swung to one side and the switch is turned off to be stable. The state shown in the figure is that the movable contact 71 is seen from the contact portion 75 where the elastic contact surface 183 of the outer surface of the rotary body 350 of the operation knob 190 of the operation knob 150 is in contact with the upper side 55 of the movable contact body 70. The state is shown in which the upper surface of the opposite side is elastically contacted, whereby the contact portion 77 of the movable contact body 70 abuts on the support body portion 51 of the movable contact body support body 50, so that the movable contact 71 is The fixed contact body 40 is separated from the fixed contact 45, and between the fixed contact body 40 and the movable contact body support body 50, that is, between the terminals 43 and 53, is in an OFF state. At this time, the arm portion 203 of the short-circuit piece 200 does not move upward from the position because the stopper portion abutting portion 211 at the tip thereof is in elastic contact with the stopper portion 59 of the movable contact body support 50. Therefore, the elastic contact portion 205 is slightly separated from the lower surface of the movable contact body 70.

次に前記操作つまみ１５０の上方向に持ち上がっている側の上面を押し込む方向に（図１１に示す矢印Ｂ方向に）押圧すると、回転体３５０が回転することでその弾接面１８３の可動接点体７０の上面への当接位置が可動接点７１側に向けて移動を始め、可動接点体７０の当接部分７５の部分に至るまでは弾発バネ１８７が押し縮められて弾発体１８１は弾発部材収納部１７５内に押し込められ、当接位置が当接部分７５の部分を通過した際に可動接点体７０は当接部分７５の部分を揺動軸として可動接点７１側が下降するように揺動を始め、押し縮められていた弾発バネ１８７の弾発力によって可動接点体７０は急速に揺動して瞬時に可動接点７１が固定接点体４０の固定接点４５に当接し、固定接点体４０と可動接点体支持体５０間、つまり両端子４３，５３間がオンする。このとき操作つまみ１５０は他方の側に揺動しきって安定する。なお両端子４３，５３がオンする際の可動接点体７０と可動接点体支持体５０間の確実な電気的接続は、前述した短絡片２００の作用によって確保される。 Next, when the upper surface of the operation knob 150 that is lifted upward is pressed in the direction of pushing in (in the direction of arrow B shown in FIG. 11), the rotating body 350 rotates to move the movable contact body of the elastic contact surface 183. The contact position of the upper surface of 70 starts moving toward the movable contact 71, and the elastic spring 187 is compressed until the contact portion 75 of the movable contact body 70 reaches the contact portion 75. When the abutting position is pushed into the emitting member storage portion 175 and the abutting position passes through the abutting portion 75, the movable contact body 70 swings so that the movable contact 71 side is lowered with the abutting portion 75 as a swing axis. The movable contact body 70 rapidly swings due to the elastic force of the elastic spring 187 which has started to move and is compressed, and the movable contact 71 abuts against the fixed contact 45 of the fixed contact body 40 instantaneously, so that the fixed contact body 40 and the movable contact body support 50 Ri between the two terminals 43 and 53 is turned on. At this time, the operation knob 150 swings to the other side and becomes stable. In addition, the reliable electrical connection between the movable contact body 70 and the movable contact body support body 50 when both terminals 43 and 53 are turned on is ensured by the action of the short-circuit piece 200 described above.

そしてこのスイッチ１−２においては、前述のように、弾発体１８１の厚み（特に弾発部材収納部１７５内のスライド部３０１の厚み）を薄く構成したので、操作つまみ１５０の揺動軸Ｋ１に沿う方向のスイッチ１―２全体の厚み寸法を容易に薄くすることができる。なおその際、弾発体１８１のスライド部３０１の揺動軸Ｋ１に直交する方向の厚み寸法を大きくすることなどによって、弾発体１８１の強度はこれを容易に強く維持しておくことができる。 In the switch 1-2, as described above, since the thickness of the elastic body 181 (in particular, the thickness of the slide portion 301 in the elastic member housing portion 175) is thin, the swing axis K1 of the operation knob 150 is configured. The thickness dimension of the entire switch 1-2 in the direction along the line can be easily reduced. At this time, the strength of the projectile 181 can be easily maintained by increasing the thickness dimension in the direction perpendicular to the swing axis K1 of the slide portion 301 of the projectile 181. .

特にこのスイッチ１−２のようにバネ収納部３０２を切り欠きで構成した場合は、弾発体１８１のスライド部３０１の厚み寸法を弾発バネ１８７の直径寸法と同じ程度まで薄くできるので、より効果的にスイッチ１−２の厚み寸法の薄型化が図れる。言い換えれば、弾発バネ１８７の直径を小さくすることなく、すなわちその耐久性や弾発力を小さくすることなくスイッチ１−２の薄型化が図れる。 In particular, when the spring accommodating portion 302 is configured with a notch like the switch 1-2, the thickness dimension of the slide portion 301 of the elastic body 181 can be made as thin as the diameter dimension of the elastic spring 187. The thickness of the switch 1-2 can be effectively reduced. In other words, the switch 1-2 can be reduced in thickness without reducing the diameter of the elastic spring 187, that is, without reducing its durability and elastic force.

さらにこのスイッチ１−２においては、揺動軸Ｋ１に沿う方向に向かってつまみ本体１７０の操作体本体部１７３から回転体取付部３０３の外側面と回転体３５０の回転軸３５３の端面が突出しない寸法となっており、この点からもスイッチ１−２の厚み寸法の薄型化が図れる。 Furthermore, in this switch 1-2, the outer surface of the rotating body mounting portion 303 and the end surface of the rotating shaft 353 of the rotating body 350 do not protrude from the operating body main body portion 173 of the knob body 170 toward the direction along the swing axis K1. From this point, the thickness of the switch 1-2 can be reduced.
