ABSTRACT:
A push switch includes a support, a switching-element assembly arranged on the support, and an actuator assembly arranged on the switching-element assembly. The switching-element assembly includes first and second contacts vertically arranged, with the second contact being elastically movable toward the first contact and making contact with the first contact when depressed by the actuator assembly. The basic actuator assembly includes an airtight enclosure of an elastic film having a domed shape and a gas enclosed therein, so that the bottom surface of the airtight enclosure depresses the second contact by a depression force onto the top surface thereof.
