ABSTRACT:
This invention relates to circuitry for the connection of a load to and disconnection of a load from an AC power source. The circuitry is specifically useful in the on/off control of such as incandescent lamps, but not exclusively so, and provides for the timed disconnection of a load when the load is connected in series with the circuitry and AC power source, or alternately provides for the timed reduction of power delivered to the load.
