ABSTRACT:
A switch unit includes a rubber contact attached to a wiring substrate, a guide plate having a pushing pin capable of being brought into contact with a contact dome of the rubber contact, and a cam plate for driving the pushing pin. The switch unit is provided in a lower case, and a slider, which has a sliding contact section in contact with the cam surface of the cam plate, is located on the cam plate so as to slide freely. The rotation of the operation lever supported on the lower case is converted into linear motion of the slider by a pin and slot, and the switch unit, slider, operation lever and an upper case are laminated so as to be mounteable in the lower case. As a result, automatic installation becomes possible, and operation can be performed by moving the operation lever only slightly.
