Abstract

An electrical switch includes a housing within which a pair of spaced apart stationary contacts are located. A center contact is positioned between the pair of spaced apart stationary contacts. A movable contact member has a fulcrum section engaged with the center contact, and a pair of arms extending outwardly therefrom. Each arm carries a movable contact, and the movable contact is adapted for movement so as to selectively establish an electrical path between the center contact and one of the stationary contacts, by movement of the movable contact member about the fulcrum section. An actuator includes a spring biased plunger engaged with the movable contact member, for providing rocking movement of the movable contact member in response to movement of the actuator. The plunger includes a head portion which moves on the surfaces of the movable contact member for moving the movable contact member between ON and OFF positions. The movable contact member and the head portion of the plunger define a matching non-linear cross-sectional configuration, to positively locate the movable contact member in its OFF position, to provide consistent placement of the movable contacts relative to the stationary contacts.
