Abstract
A wall switch is provided for an automatic lighting control system for a space equipped with multiple lamps for illuminating the space and multiple power circuits for supplying power to different groups of said lamps. The wall switch includes at least one sensor detecting conditions or events that indicate that increased illumination of the space by the lamps is needed or decreased illumination of the space by the lamps is allowable. Normal control of the electric lighting is thus automatic to a large degree. But, at least two manually operable switches are coupled to the microcontroller to provide the microcontroller with ON and OFF command signals for at least two of the lamp groups powered by different power circuits. A separate status indicator light for each of the switches is controlled by the wall switch and provides an indication of whether the lamp group associated with each manual switch is currently ON or OFF as a safety and economy feature.
