Claim:
1. A switch system, comprising: a snap action switch configured to move, with snap-action, from a first switch position to a second switch position; a housing, wherein the snap action switch is disposed within the housing; and a heated actuator contacting an operating plunger and configured to selectively supply an actuating force to, and remove the actuating force from, the operating plunger, wherein the heated actuator is separate from the housing, wherein the operating plunger extends between the heated actuator and the housing, wherein the operating plunger extends into the housing through an opening in the housing and is disposed adjacent to the snap action switch within the housing, wherein the operating plunger is configured to selectively receive the actuating force, and upon receipt of the actuating force, to retain the snap action switch in the first switch position, wherein 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; and wherein the operating plunger comprises a dielectric material having a thermal conductivity of less than or equal to 23 W/m-k and a dielectric strength of less than or equal to 15 kV/mm per ASTM-D149.
