The relay is adapted to open circuit in response to a predetermined temperature. A heater element responsive to the opening of the relay is shunted across the relay. When the relay opens, power is shunted to the heater for maintaining the relay at least at the predetermined temperature thereby holding the relay open while the load remains connected to said power source.
