1. A switch device comprising:
- a case having a bottom wall and a top opening;
two switch elements assembled in the case;
a common leaf spring whose restoring force is applied to the two switch elements; and
a cover that presses the leaf spring and covers the top opening;
wherein each of the switch elements comprises;
stationary contacts that are fixed to the bottom wall of the case;
a conductive plate that is disposed on the bottom wall and is tiltable to move into and out of contact with the stationary contacts; and
a driver disposed on the conductive plate, the driver being rotatable around a shaft thereof and movable vertically;
wherein the driver comprises;
a protruding receiver which protrudes from the case; and
a sliding portion that slides on a slope of the conductive plate when the protruding receiver is pressed downward; and
wherein the leaf spring comprises;
a compressed portion which is resiliently compressed by the cover; and
a pair of pressing strips which connect with the compressed portion and resiliently urges the shaft of the driver towards the bottom wall of the case.

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.
