Claims

[Scope of utility model registration request]

A metal dish-shaped inverted leaf spring is mounted on an insulating substrate provided with an outer circumferential electrode, a center electrode at the center of the outer circumferential electrode, and a drawing pattern drawn out from the center electrode to the outside of the outer circumferential electrode. In the switch, a switch is provided, in which a part of the outer periphery of the disc-shaped inverted leaf spring is provided near the lead-out pattern on the insulating substrate, with the center part facing the center electrode and in contact with the outer periphery electrode. The switch is provided with a protruding part on which the part rests, and the dish-shaped inverted leaf spring partially floats above the insulating substrate, is spaced apart from the drawer pattern, and is insulated from the drawer pattern.
