A plug adapted to fit in a standard electrical outlet and supply power through a cord to an electrical device is provided with a thermostat and bistable resettable switch. When one of the plug's prongs is overheated, indicating an overload or short circuit, the thermostat actuates the switch and cuts off power to the electrical device. When the malfunction is repaired, the switch is reset to restore the circuit.
