PUSH-BUTTON SWITCHES

摘要

Push-button switches are provided with a housing having opposed pairs of side walls defining an interior space, and an opposed pair of fixed contact members. A push-button assembly is received within the interior space of the housing for reciprocal movements between extended and retracted positions. The push-button assembly including a pair of opposed side windows having lower extents established by a bridge wall. A spring exerts a bias force to move the push-button assembly into its extended position. A generally inverted V-shaped slide contact member is movable with the push-button assembly between its extended and retracted positions, and includes a pair of resilient legs each having an outwardly curved contact region. The contact regions serve to contact the pair of fixed contact members when the push-button assembly is moved into one of its extended and retracted positions whereby an electrical circuit is made, and breaks contact with at least one of the fixed pair of contacts when the push-button assembly is moved into the other of its extended and retracted positions, whereby an electrical circuit is broken. The slide contact member further includes terminal end flanges extending from the curved contact regions, the terminal end flanges being positioned so as to contact a respective bridge wall of an associated side window and thereby limit the extent of outward resilient displacement of the legs of the slide contact member.
