ABSTRACT:
A switch, typically one used as a wall switch for the control of lighting in residences and commercial establishments, has a handle which is operable between a full off position in which the switching circuit is completely disconnected from a source of electrical power, and a use position in which the handle, while remaining stationary, becomes a touch-type control for operating the switch circuit between its "on" and "off" modes.
