Switch system with high temperature operating plunger

A switch system, comprising:

• a housing;
• a snap action switch disposed within the housing and configured to move, with snap-action, between a first switch position to a second switch position;
• an operating plunger extending through an opening in the housing and contacting the snap action switch, the operating plunger coupled to selectively receive an actuating force and configured, upon receipt of the actuating force, to move the snap action switch to and retain the snap action switch in the first switch position, the operating plunger 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
• a heated actuator contacting the operating plunger and configured to selectively supply the actuating force to, and remove the actuating force from, the operating plunger, wherein the heated actuator is outside of the housing,
• 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.

A switch system, comprising:

• a snap action switch disposed within a housing and configured to move, with snap-action, between an open switch position to a closed switch position;
• an operating plunger extending through an opening in the housing and contacting the snap action switch, the operating plunger coupled to selectively receive an actuating force and configured, upon receipt of the actuating force, to move the snap action switch to and retain the snap action switch in the open switch position, the operating plunger further configured, upon removal of the actuating force, to allow the switch to move from the open switch position to the closed switch position;
• and
• a heated actuator contacting the operating plunger and configured to selectively supply the actuating force to, and remove the actuating force from, the operating plunger,
• 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.
