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 simplified electric switch is disclosed which includes: an insulating base (3) which may include an electronic circuit and printed circuit board, a switch cover (4) mounted on the base; terminals (1a, 1b, 2a, 2b) disposed on the base, internal lead wires (16a, 16b, 17a, 17b) opposed to each other and connected to the terminals, a rocking type movable contact element (6) in the form of an electrically conductive plate and a push member (7) which may be a slide member, toggle member, or rotary member. The movable contact element has a gently curved belly portion (15), reversely bent shoulder portions (14) on opposite sides of the belly portion, and polygonal pyramidal shaped contact ends (8a, 8b, 9a, 9b). The belly portion is centrally provided with a projection (12). The movable contact element is mounted on the insulating base and rocks about the projection.
