Disclosed is a capacitance responsive and touch sensitive power control circuit for an incandescent lamp or the like. A bidirectional AC semiconductor switch, such as a TRIAC, operatively connects and disconnects a lamp in series with power supply terminals, and the bidirectional semiconductor switch is alternately driven to conduction and nonconduction by a bistable flip-flop. A touch signal input circuit provides a triggering signal for the bistable flip-flop in response to body capacitance input signals applied thereto.
