Abstract: A push-button switch comprises a housing having a substantially cylindrical interior portion. It also includes a movable switching member, disposed substantially within the interior of the housing and having a reciprocally movable plunger with successive released, latched and depressed positions relative to the housing interior portion. Functional surfaces of substantially cylindrical form are disposed adjacent and in a substantially fixed position relative to the interior portion of the housing and include guiding surfaces aligned in the direction of movement of the plunger. The plunger has members, interengaging with the guiding surfaces, for preventing rotation of the plunger during reciprocal movement of the plunger. The movable switching member also includes a rotatable latch ring, preferably C-shaped, disposed on the plunger and having a radially extending lug. The plunger also has members for holding the rotatable ring in a fixed latitudinal position about a portion of the plunger.
