Switch Time Delay Apparatus
US Patent:
5051607, Sep 24, 1991
Filed:
Jul 5, 1990
Appl. No.:
7/548563
Inventors:
John E. Dalton - Grand Junction CO
International Classification:
H01H 4302, H05B 3900
US Classification:
307141
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.
