Abstract
An illuminated push-button switch assembly includes a tubular housing closed at one end thereof by a base member having a lamp receptacle disposed within the housing and switch-mounting arms disposed externally of the housing. A leaf switch is mounted between the switch mounting arms and the leaf contacts thereof extend through an opening in the base member into the housing alongside the lamp. A cup-shaped actuator is disposed for longitudinal movement within the housing and has a pair of legs respectively extending through complementary openings in the base member and respectively surrounded by helical compression springs for resiliently biasing the actuator to a normal rest position. The actuator has a light-transmitting cover which covers the other end of the housing. A cam surface on the actuator cam-actuates the switch contacts upon depression of the actuator button.
