摘要： Disclosed is a capacitance responsive and touch sensitive power control system for successively switching different loads across a power supply. The system includes a pair of bidirectional triggerable switches, such as semiconductor TRIACS, which operatively connect and disconnect different loads in series with a single power supply. These switches are alternately driven to conduction and nonconduction in a predetermined sequence by a pair of bistable flip-flops, the inputs of which are controlled by body capacitance signals applied to a common input circuit of the system. A novel threshold and delay noise discrimination network is interconnected between this input circuit of the system and the pair of bistable flip-flops and it discriminates between body capacitance signals and line noise in order to minimize false operation of the system due to line noise. In a preferred embodiment of the invention, the triggerable switches are a pair of TRIACS which respond to a predetermined sequence of conductive states of the pair of flip-flops, respectively, to provide successively higher power levels to multiple loads in response to successive body capacitance signals received at the touch signal input circuit.
