Abstract

An overheat-protection device with a cord that includes a transmission wire to transmit electrical power and a sensor wire to transmit a signal, a plug attached to an end of the cord, and a thermistor includable in the plug and connected to the sensor wire. The signal may be received and/or analyzed by a sensing device, which may control a switching device to open and/or close a power circuit. The thermistor may detect a level of heat, which may be communicated as a signal via the sensor wires. The signal may be definable by the thermistor varying a level of resistance to the signal responsive to the level of detected heat. The thermistor may be a NTC thermistor and may be constructed from a thermal plastic or a ceramic.
