ABSTRACT:
An electronic switching system, designed to automatically illuminate and delay in extinquishing 115 V 60 Hz outdoor/indoor lights and electrical wall receptacles. The system includes an automatic sensing circuit which detects open and closed circuits, at its input sense terminals wherein sensors are connected. An open detection illuminates lights and energizes wall receptacles connected to the system's input/output screw-type barrier block; and a closed detection thereafter keeps lights and wall receptacles supplied with 115 V 60 Hz for the duration of the delay adjust setting, then exitinguishing power. A regulation pin is incorporated for connecting an electronic clock for regulating the automatic sensing circuit's operation within a predetermined time. A manual power on/off circuit is also included, for operating the system independently of the automatic sensing. When placed in the "OFF" position the manual power on/off circuit initiates a delay in extinquishing 115 V 60 Hz. The system is mounted within an enclosure having input and output power cords protruding therefrom as a table model, and mounted on a modified switch face plate as a wall model.
