ABSTRACT:
A switch construction including opposed contacts positioned on a base and a bridging contactor slidable between different switch positions. The design of the contacts on the base includes an upper section defining a first surface engageable by a tab formed on the sliding contactor. Second surface portions offset relative to the first surface provide engagement with shoulders defined by the sliding contactor. Resilient means press the sliding contactor against this upper section in a fashion such that the shoulders operate to limit the movement of the sliding contactor. The separate engagement of the tab and shoulders provide separate available current paths for the switch.
