Abstract
A bimetallic disc actuated thermostatic switch with thermal override comprises a base, a fixed contact on the base, a movable contact and a bimetallic disc which moves the movable contact into and out of engagement with the fixed contact to effect or interrupt continuity therebetween. A thermal override pellet which melts or deforms in response to an excessive temperature is provided in a cavity in the base and the fixed contact is mounted on a resilient arm which overlies the pellet. When an excessive temperature is reached, the pellet fuses or deforms and the fixed contact arm and the fixed contact move toward the base to separate the fixed and movable contacts even when the latter is in its normally engaged position.
