摘要： A nonresettable thermally actuated switch comprising a case of electrically conductive material, a first power lead connected to the case, a second power lead electrically insulated from the case, a deformable connector of conductive material in electrical contact with an inside surface of the case and with the second lead thereby to complete a circuit. The switch further includes an insulator biased toward the connector by a spring but separated therefrom by a body of fusible material. When heated above a predetermined temperature the fusible material melts and the insulating member moves against the connector mechanically deforming the connector away from the inside surface of the case and electrically insulating the connector from the case thereby to break the circuit.
