The one in Figure 3 is seesaw lever 1. By operating the spring, the substantially U-shaped movable contact piece 2, which has spring properties and is held on the common terminal 3 assembled in the box-shaped case 5, is reversed by the spring pressure and connected to the individual terminal 4. The switch is changed by changing the contact. In addition, in the case shown in FIG. 4, when the seesaw lever 6 is operated, the pin 8 incorporated in the seesaw lever 6 is pressed by a spring 7 and the box-shaped case 12 is moved.
The switch is switched by inverting the movable contact piece 9 held at the common terminal 1° incorporated in the switch to change the contact with the individual terminal 10.

ッチの切換えを行っている。EXAMPLE Hereinafter, an example of the present invention will be explained with reference to FIGS. 1 and 2 of the drawings. In the one shown in FIG. 1, by operating a seesaw lever 13, a substantially U-shaped movable contact piece 14 with spring properties is held on a common terminal 16 built into a box-shaped case 17. is reversed by the spring pressure, and the contact with the individual terminal 16 incorporated in the case 17 is changed, thereby switching the switch. In addition, in the case shown in FIG. 2, by operating the seesaw lever 18, a pin 2o incorporated in the seesaw lever 18 is pressed by a spring 19, and a common terminal incorporated in a box-shaped case 24 is opened. 22
The switch is switched by inverting the movable contact piece 21 held in the case 24 and changing the contact with the individual terminal 23 which is also incorporated in the case 24.
