Claims

[Scope of utility model registration request]

A wafer having a clip-shaped first fixed contact and another second fixed contact, a movable contact made of a torsion coil spring that is in constant contact with the second fixed contact, a slider that presses the movable contact, and a slider that presses the movable contact. The switch includes a lid through which a slider is inserted and covers the opening of the wafer, and the movable contact contacts and separates from the fixed contact by moving the movable contact with respect to the first fixed contact by the slider. A switch device characterized in that the wafer and the lid are each provided with a curved guide surface, and the free end of the torsion coil spring is guided by the guide surface.
