Abstract: Apparatus for interrupting power to a plurality of parallel loads such as lighting circuits and selectively reapplying power to the loads includes a first switch serially interconnecting the loads to a power line. Second switch circuits are serially connected with each load whereby interruption of power to a load for a predetermined period of time opens the switch circuits. The switch circuits include bidirectional conduction devices such as triacs which require a gating signal before becoming conductive. A resistor-capacitor circuit provides a gating signal to the triac to maintain conduction thereof for the predetermined period of time.
