Time-delayed power switching device and methods of use
Abstract:
A time-delayed power switching device for providing power pass-through and timed off conductive pathways to one or more light outputs comprises a power source input, one or more first conductive pathways, one or more second conductive pathways, at least one timing circuit, and at least one relay. The time-delayed power switching device controls power from a power source electrically coupled though the power source input to the timed off conductive pathways by operation of the at least one timing circuit controlling the at least one relay. The relay has a first position adapted to energize the second conductive pathways when receiving a first signal from the timing circuit, and a second position adapted to de-energize the second conductive pathways when receiving a second signal from the timing circuit. Additionally, methods of using one or more time-delayed power switching devices to retrofit lighting areas are disclosed.
