  • Electrical safety circuit with a breakable conductive element
    Patent number: 5801914
    Abstract: An electrical safety circuit for discontinuing the operating power to an electrical device when overheat conditions are present. The safety circuit includes a conductive element in thermal proximity to at least one of the circuit elements of the electrical device that is energized by the operating power. The conductive element is structured so as to quickly break in response to high temperatures. A switching circuit is included which responds to a break in the conductive element by discontinuing the operating power to the electrical device.
