ABSTRACT:
A thermal relay having main contacts and normally closed auxiliary contacts, a thermally responsive actuator for sequentially operating the main and normally closed auxiliary contacts, and an electric heater for causing said thermally responsive actuator to move. The power supplied to the electric heater is controlled by the auxiliary contacts so that the position of the thermally responsive actuator in the operated position is self-regulated. Because the position of the thermally responsive actuator in the operated position is self-regulated, the time for deactuation of the relay is reduced from prior art relays. One use of the relay of the invention is that of a cornering relay in an automobile signal light system whereby the relay is actuated by the signal light flasher to actuate a cornering lamp.
