ABSTRACT:
A touch controlled electronic switching circuit in which the body capacitance of the person actuating the device is coupled in series with current limiting resistors and a capacitor with the junction coupled to a logic circuit which responds thereto to provide a direct current control signal. The logic circuit has an output coupled to the gate terminal of a Triac coupled to a load for selectively applying current to said load during both half-cycles of each cycle of the line voltage supplied to the Triac and load.
