ABSTRACT:
A push switch includes a movable contact, and a drive body. The movable contact includes an annular part with a circular central hole and four leg parts inclined and extruded downward from the outer circumferential end of the annular part by way of a deflection part, formed in a shape bulging upward at the circular central hole side. The drive body includes a flat plate with the lower end abutting against the position of the inner side of the deflection part of the movable contact, and an operation part of a smaller diameter than the abutting position provided on the flat plate, if the operation part is pressed and manipulated at a position remote from the center, a light and responsive click feel is obtained.
