1. A switch device adapted for mounting on a wall comprising:

  • a switch with a frame and a switch actuator projecting from said frame, said actuator being movable from an initial position to a connecting position upon applying pressure thereto, and from the connecting position to the initial position upon release of the pressure; and

    a plunger acting on said switch actuator and having a press knob and a hollow spring member formed of a resilient material, said hollow spring member having a base in contact with said switch actuator and having a width substantially greater than the width of said switch actuator, said hollow spring member acting on said switch actuator upon application of pressure to said press knob to move said switch actuator from its initial position to its connecting position, said hollow spring member moving said switch actuator to the connecting position without being substantially deformed, upon further application of pressure to said pressure knob, said spring member engaging said frame on opposite sides of said switch actuator and yielding to pressure by being deformed at a location where said switch actuator engages said hollow spring member.
