ABSTRACT:
A touch switch having two electrodes, one of which is driven by a pulse signal having a fast leading edge, and the other of which is connected to a logic detector circuit which is selectively triggered by said leading edge. The detector circuit operates to compare the pulse signal passed via the electrodes with one passed directly from the drive pulse generator, and gives an output to a triac trigger circuit dependent upon the amplitude of the signal coupled from one electrode to the other.
