Abstract: A simplified electric switch construction is disclosed. The switch construction comprises at least a pair of confronting first and second terminals each having a bridge portion, a conductive resilient plate having one end shaped as a polygonal pyramid disposed in confronting relation to the bridge portion of the first terminal and an opposite end connected to the bridge portion of the second terminal, a presser for depressing an intermediate portion of the resilient plate to bring the tapered end into contact with the bridge portion of the first terminal, and a driver for depressing the presser. The switch construction may contain a printed-circuit board with an electric circuit thereon.

Abstract: A switch comprises a movable conductive contact in the form of a curved plate having an arcuate cross section, and terminals having ends projecting into a cavity. The movable conductive contact is pressed into the cavity to cause an end of the contact to be resiliently held against and slidably supported on the ends of the terminals.
