Abstract
A switch device includes two switch elements, both elements being disposed in a case and given restoring force by a common leaf spring; a cover which closes a top opening of the case; and an operating knob having two projections for selectively activating the switching elements. The leaf spring includes a compressed portion which is resiliently compressed by the cover, a pair of pressing strips which resiliently presses against each shaft of a pair of drivers of the switching elements. The operating knob presses a protruding receiver of each of the drivers, thereby selectively tilting a pair of conductive plates to output a switch ON signal.
