Abstract:
A time delay apparatus configured to connect in parallel with a common single pole switch. For time delay operation the switch is toggled on and off again within a short time span defined as the trigger window period. This triggering results in the circuit providing power to the load for a period of time predetermined by the user, after which the circuit automatically interrupts power to the load. For manual operation the switch is turned on and left on longer than the trigger window period, after which turning the switch off results in interruption of power to the load similar to a standard wall switch.
