The guided portion 54 is arranged between the short-circuit members 26. The first housing 28 is provided with a groove-shaped guide portion 56 into which the guided portion 54 is inserted. The guide portion 56 is provided between the first terminals 14 and between the second terminals 16 in the first housing 28. The guided portion 54 enters the guide portion 56 and determines the direction of the reciprocating motion of the short-circuit member 26. The length direction of the guided portion 54 faces the length direction of the short-circuit member 26, and the short-circuit member 26 can be reciprocated in the length direction. The tip of the guided portion 54 may be gradually tapered so that the guided portion 54 can easily enter the guide portion 56.

短絡部材２６を往復運動させるために、固定部材５２に作用部材５８が取り付けられている（図３、図４）。作用部材５８は長板状であり、その長さ方向は短絡部材２６の長さ方向に対して垂直方向を向いている。作用部材５８の両端部分は垂直方向に折れ曲がっている。作用部材５８の両端部分に第１凹部６０が形成されている。 An acting member 58 is attached to the fixing member 52 in order to reciprocate the short-circuit member 26 (FIGS. 3 and 4). The working member 58 has a long plate shape, and its length direction is perpendicular to the length direction of the short-circuit member 26. Both ends of the working member 58 are bent in the vertical direction. First recesses 60 are formed at both ends of the working member 58.

第２筐体３０に支点部材６２が取り付けられている(図１）。支点部材６２は長板であり、その長さ方向は作用部材５８の長さ方向と同じ方向を向いている。支点部材６２の両端部分は垂直方向に折れ曲がっている。支点部材６２の両端部分に第２凹部６４が形成されている。 A fulcrum member 62 is attached to the second housing 30 (FIG. 1). The fulcrum member 62 is a long plate, and its length direction is the same as the length direction of the working member 58. Both ends of the fulcrum member 62 are bent in the vertical direction. Second recesses 64 are formed at both ends of the fulcrum member 62.

本願はレバー６６を備える（図６）。レバー６６は両端部が対向するように折れ曲がった板状体または棒状体である。板状体または棒状体の中央部分が直線状になっている。レバー６６の対向する部分に第１凸部６８と第２凸部７０が備えられている。 The present application comprises a lever 66 (FIG. 6). The lever 66 is a plate-shaped body or a rod-shaped body bent so that both ends face each other. The central part of the plate-shaped or rod-shaped body is straight. A first convex portion 68 and a second convex portion 70 are provided on opposite portions of the lever 66.

レバー６６の第１凸部６８は第１凹部６０に入り、第２凸部７０は第２凹部６４に入る。各凸部６８、７０を各凹部６０、６４に入れた状態でレバー６６の中央部分を持って、レバー６６を回転させる。第２凸部７０が支点、第１凸部６８が作用点になり、作用部材５８を移動させることができる（図７、図８）。作用部材５８と短絡部材２６は一体になっているため、作用部材５８の移動によって短絡部材２６が移動される。短絡部材２６が移動されることで、第３接触子２２と第４接触子２４の短絡状態と絶縁状態を切り替えることができる（図５（ａ）、（ｂ））。 The first convex portion 68 of the lever 66 enters the first concave portion 60, and the second convex portion 70 enters the second concave portion 64. With the convex portions 68 and 70 inserted in the concave portions 60 and 64, the lever 66 is rotated by holding the central portion of the lever 66. The second convex portion 70 serves as a fulcrum and the first convex portion 68 serves as an action point, and the working member 58 can be moved (FIGS. 7 and 8). Since the working member 58 and the short-circuit member 26 are integrated, the short-circuit member 26 is moved by the movement of the working member 58. By moving the short-circuit member 26, the short-circuit state and the insulation state of the third contact 22 and the fourth contact 24 can be switched (FIGS. 5A and 5B).

第１筐体２８または第２筐体３０にレバー６６の両端および第１凸部６８が入る隙間７２を設ける（図１）。レバー６６の両端を隙間７２に入れ、さらに第１凸部６８を第１凹部６０に入れる。 The first housing 28 or the second housing 30 is provided with a gap 72 into which both ends of the lever 66 and the first convex portion 68 are inserted (FIG. 1). Both ends of the lever 66 are inserted into the gap 72, and the first convex portion 68 is further inserted into the first concave portion 60.

図１に示すように、作用部材５８の両端部分に、作用部材５８の長さ方向に対して垂直方向を向き、Ｌ字形状になった停止部７４を設ける。第１筐体２８または第２筐体３０の側部に、作用部材５８の当接部７６を設け、停止部７４が当接部７６に当たるようにする。作用部材５８を所定位置で停止させることができる。 As shown in FIG. 1, stop portions 74 having an L-shape facing perpendicular to the length direction of the working member 58 are provided at both ends of the working member 58. A contact portion 76 of the working member 58 is provided on the side portion of the first housing 28 or the second housing 30, so that the stop portion 74 hits the contact portion 76. The working member 58 can be stopped at a predetermined position.
