Abstract
A snap-action electric switch comprising a housing; a first contact member which is of resilient flexible material and includes a frame defining a central window, the frame lying generally in a plane and consisting of a base, two opposite sides, and a tip, the base being fixed in the housing and the remainder of the frame being movable; a fulcrum aligned with the window and fixed in the housing; a second contact member, fixed in the housing adjacent to the tip of the first contact member; a stop fixed in the housing adjacent to the tip; and an actuating member having a central bore the axis of which is transverse to the general plane of the frame, and the cross section of which is aligned with the window, the actuating member being able to reciprocate relatively to the housing in the direction of the axis of the bore, and the actuating member having abutments cooperating with the sides of the frame; the first contact member including a tongue projecting into the window from adjacent to the tip of the frame, and terminating in an end which is in compressive engagement with the fulcrum.
