ABSTRACT:
A push-button electric switch particularly adapted for use in printed circuit boards in which the base member has a plurality of terminals thereon and the actuating plunger may incorporate one or more bridging contact members which cooperate with the terminals to provide varying switching configurations, such as a single pole, single throw switch or double pole, double throw switch. The base is keyed to the actuating plunger and housing so that the housing and plunger may be assembled on the base in either one of two positions to provide with a single bridging contact in either one of two configurations with respect to the terminals connecting to the printed circuit board. The assembly provides for a recessed or hollow operating shaft of the plunger and an upstanding post on the base member for providing a mounting for an illumination light for key top illumination and permitting connection of the electric conductors from the illumination light through the base member to the printed circuit board.
