Abstract
A switch system includes a snap action switch, an operating plunger, and an actuator. The snap action switch is configured to move, with snap-action, from a first switch position to a second switch position. The operating plunger is disposed adjacent to the snap action switch and is coupled to selectively receive an actuating force. The operating plunger is configured, upon receipt of the actuating force, to retain the snap action switch in the first switch position. The operating plunger is further configured, upon removal of the actuating force, to allow the switch to move from the first switch position to the second switch position. The actuator contacts the operating plunger and is configured to selectively supply the actuating force to, and remove the actuating force from, the operating plunger. The operating plunger comprises a dielectric material having low thermal conductivity.
