  • Appliances having resistive heating elements and thermal protective apparatus used therewith
    Patent number: 5489762
    Abstract: A thermal protector (70, 70') is shown particularly suitable as a safety back-up mechanism for appliances having electrically energizable resistance heaters. The thermal protector has first (72, 72') and second (74, 74') electrically conductive housing members joined together through an electrically insulating gasket (76). A thermostatic snap acting disc (86) is cantilever mounted on one of the housing members and adapted to move between positions in and out of electrical engagement with the other housing member in dependence upon temperature. The snap acting disc (86) has an actuation temperature selected from approximately 70.degree. C. to 175.degree. C. and, for non-resettable applications, a reset temperature of -35.degree. C.
