れる。Embodiment An embodiment of the present invention will be described with reference to the drawings. The metal case 1 formed in a substantially U shape has, for example, a mounting portion 1a for screw mounting on one side. The metal sliding body 2 is biased by the coil spring 3 and slidably held in the holes 1b and 1c of the metal case 1. The insulating case 4 has, for example, convex portions 4a and 4b at both ends thereof.
Is fitted in the notches 1d and 1e of the metal case 1 and is caulked and attached together with a lid which will be described later to connect with the metal case 1. The metal interposer 5 having a circular cross section is located in the recess 4c of the insulating case 4, and the inner wall of the recess 4c is opened in the direction in which the sliding body 2 is pushed (the direction against the biasing force of the coil spring 3). It is tilted so that it opens toward the side. The metal leaf spring 6 presses the interposer 5 inwardly of the recess 4c. For example, one end is held in the groove 4d on the inner wall of the insulating case 4, and the other end is inserted and held in the hole 7a of the terminal 7. By doing so, the terminal 7 is extended from the leaf spring 6.
The base of the terminal 7 is, for example, the groove 4 of the insulating case 4.
It is inserted into and held by e, and its end is guided to one of the guide grooves 4f of the insulating case 4 and led out to the outside. The insulating lid 8 presses the outer edge of the terminal 7, and the protruding portions 4a.4b of the insulating case 4 are pressed.
At the same time, it is caulked and attached to the notches 1d and 1e of the metal case 1.

介在子５−板バネ６−端子７が形成される。Further supplementing the above-mentioned configuration, the sliding body 2 has a coil spring 3
When the sliding body 2 slides against the urging force to reach the position of the dotted line, the side edge 2a of the sliding body 2 rotates the interposer 5 diagonally from the recess 4c against the pressing direction of the leaf spring 6 to the position of the dotted line. While pushing out, the side edge 2a contacts the interposer 5. Also, if the sliding body 2 returns to its original position, the sliding body 2 and the interposer 5
Contact with is cut off. When the sliding body 2 and the interposer 5 come into contact with each other, a metal case 1-sliding body 2-is formed as a conduction path.
The interposer 5-leaf spring 6-terminal 7 is formed.

在子５の移動もスムーズに行える。According to such a configuration, the sliding body 2 itself is the metal case 1
When the sliding body 2 slides against the urging force of the coil spring 3, the side edge 2a of the sliding body 2 has a metal interposer 5 and a leaf spring 6 interposed therebetween. Since it can be electrically connected to the terminal 7, the mechanism part and the conductive part can be rationally configured, which contributes to downsizing of the switch, and partial wear of the interposer 5 is unlikely to occur, so that the sliding body 2 The contact performance with can be maintained for a long period of time, and furthermore, the slanted surface of the recess 4c allows the interposer 5 to move smoothly.
