Abstract
A retained and a removable circuit connect together to form a closed circuit. A switching mechanism is connected between the retained and removable circuits and to a circuit break load. Upon disconnection of the circuit break load and/or the removable circuit, the switching mechanism automatically switches from an open circuit to a closed circuit to form a closed circuit with the retained circuit.
