ABSTRACT:
A touch dimmer switch incorporating an integrated circuit for controlling a thyristor dimming circuit, has a touch control connected in a high impedance, unidirectionally conducting circuit, and a filter circuit for filtering out ambient electrical noise. The touch control is isolated from the AC power source so that the polarity of connection to the power source is not critical.
