An electronic switch has a sensor input responsive to a person's touch. Manual contact is sensed by a CMOS input of a one-shot multivibrator initiating the output which is used to toggle a flip-flop circuit off or on. The flip-flop output is connected to the trigger circuit of a silicon controlled rectifier, which in turn completes a circuit through a load. The switch may be a single pole, single throw switch, or if flip-flops are connected together in cascaded arrangement, a three position switch is formed.
