ABSTRACT:
A push switch includes an electrically insulating cylindrical base defining an interior space in which an actuator is movably disposed. Fixed contacts are associated with the base, while an inverted V-shaped contact is carried by the actuator so as to be capable of coming into contact with the fixed contacts and thereby making and breaking an associated electrical circuit. The base includes stepped detents which coact with terminal engagement ends associated with elastically deformable engagement legs of the actuator so as to limit the actuator's extent of movement. A resilient protective cap collectively covers an upper region of the insulating base and the actuator and is coupled to the base by a pin formed on the base being engaged within a recess formed in the cap.
