ABSTRACT:
A timing circuit is described which includes a storage capacitor, a switch, and a load to be energized in a closed loop. A programmable timer, energized by the storage capacitor controls the switch. An external potential is applied to charge the capacitor and hold the timer in a reset mode. Upon removal of the external potential the timer is enabled and closes the switch a predetermined time thereafter.
