Abstract
A miniature electrical switch is closed when a pusher (44) is pushed forwardly (F) to snap down a snap dome tripping member(36) and push a contact blade (50) against a contact part (28). Forward sliding of the actuator is converted into downward movement of the snap dome, by a rigid lever (48) of generally T shape, with a rear branch (51) having laterally spaced trunnions (60) for pivoting and a center section (52) with a cam follower upper surface (76). A ramp (94) at the front of the push member depresses the cam follower as the actuator slides forward. The trunnions are of largely rectangular cross section and pivot on an edge (130).
