Abstract
A switch assembly includes a housing having a plurality of terminals at one end and a push-button at the opposite end. An actuator mechanism is disposed in the housing and is connected with the push-button. The actuator mechanism is operable to move movable switch contacts relative to stationary switch contacts upon manual actuation of the push-button. A printed circuit extends between terminals at one end of the housing and the push-button. The printed circuit has a zig-zag portion disposed within the housing to accommodate movement of the push-button relative to the housing. The push-button is at least partially illuminated by light sources mounted on the printed circuit. The actuator mechanism includes a plurality of longitudinally extending actuator levers which are connected with the movable switch contacts and are pivotally connected with an actuator link. During actuation or release of the push-button, actuator link springs store energy which assists actuator lever springs in effecting rapid movement of the movable switch contacts relative to the stationary switch contacts.
