When the leaf spring 6 rotates clockwise about the V groove 3f of the central terminal 3, the conductor plate 4 also rotates clockwise about the contact point I between the tip of the conductor plate 4 and the lower surface of the slide 7. . When the leaf spring 6 reaches the reversal point, which is the dead center position where the leaf spring 6 has been compressed to the maximum, the conductor plate 4 moves on its own, and the movable contact 4 a of the conductor plate 4 abuts against the fixed contact 2 a of the fixed terminal 2. State, and the circuit is turned on, as shown in FIG. At this time, the conductor plate 4 is held between the fixed contact 2a of the fixed terminal 2 and the receiving portion 3d of the central terminal 3, and the slide 7 is also locked by the action of the tampin 7b engaging with the cam groove 7d.

Return to In this return process, the right vertical portion of the drive groove 7g in FIG. 18 abuts on the operation protrusion 6c of the leaf spring 6, which causes the counterclockwise direction in FIG. Then, it acts so as to pull back the leaf spring 6 until the slide 7 returns to off. Accordingly, the conductor plate 4 also returns from the position shown in FIG. 18 to the position shown in FIG. 17 beyond the reversal point of the leaf spring 6 in accordance with the position of the leaf spring 6, and the fixed contact 2a and the movable contact 4a leaves and returns to the off state.

できる。As described above, since the conductor plate 4 is driven by directly pressing or pulling back the leaf spring 6 by the driving groove 7g formed in the slide 7, the pressing force on the slide 7 is reduced. The conductor plate 4 can be operated substantially as it is or by amplifying it, and operability can be improved.

件になっており、小型化し難いという欠点がある。By the way, in the above-mentioned conventional example, in order to swingably support the movable contact 4a, the locking groove of the front locking portion 5c of the support plate 5 must be formed in the conductive plate 4. The support plate 5 is attached to the opening 4b of the conductor plate 4 from above so as to lock the projection 5d of the support plate 5 on the opposite locking edge 4d side while locking to the locking edge 4c side. The engaging protrusion 6b of the leaf spring 6 is engaged with the engaging edge 4d of the conductor plate 4, and the engaging portion 6a at the other end of the leaf spring 6 is brought into contact with the inner surface of the support plate 5 on the side of the movable contact 4a. Thereby, the leaf spring 6 is resiliently moved between the edge of the conductor plate 4 and the contact portion of the support plate 5 in a direction away from each other, and the conductor plate 4 and the support plate 5 and the leaf spring 6 are separated from each other. The three members are integrated and attached to the central terminal 3, so that the structure is complicated and the assembling work also requires skill. Further, the support plate 5 is an essential component in order to suppress the bounce of the central terminal 3 which occurs due to the swing of the movable contact 4a, and there is a disadvantage that it is difficult to reduce the size.

The reversing cam surface portion 30c is provided integrally with the side surface of the wall portion 11e (or 11f) of the case 11, and the reversing cam surface portion 30c has a mountain-shaped top portion 30c3 and slopes on both sides from the top portion 30c3 as in the above embodiment. It comprises a first cam surface 30c1 and a second cam surface 30c2. The outer peripheral surface of the coil portion 24a of the torsion coil spring 24 of the conductive plate 23 slides on the first cam surface 30c1, the second cam surface 30c2, and the top portion 30c3 while elastically contacting. According to such a configuration, since the reversing cam surface portion 30c with which the coil portion 24a of the torsion spring 24 contacts is made of metal, it does not wear even if the coil portion 24a moves while contacting for a long time. The reversing cam surface 30c
Is integrated with the side surface of the wall 11e (or 11f), so that the guide side 22c does not rattle or deform. Further, since the conductor plate 23 is oscillated in the central terminal 30 which is substantially U-shaped when viewed from above, the elastic force of the coil portion 24a of the torsion spring 24 is received by the central terminal 30. Since the elastic force is not applied to the portions 11e and 11f, the thickness of the walls 11e and 11f can be reduced, and the size and weight of the device can be reduced. Configurations, operations, and operations not particularly described in the description of the second embodiment are the same as those of the above-described embodiment.
