ABSTRACT:
A control circuit for connecting a load to a voltage source includes an electronic holding circuit having latched and unlatched states. When latched, the electronic holding circuit connects the load to the voltage source. A thermal device responsive to excessive current demand by the load automatically places the holding circuit in its unlatched state, and disconnects the load from the voltage source.
