ABSTRACT:
A touch control circuit is disclosed, which delivers power at any one of a plurality of different levels. To accomplish this, a line cycle delay timer provides a plurality of output signals, each signal being spaced apart in time from the line voltage zero crossing time and from each other. Power level memory and gating means gate the timer output signals to the power delivery means so as to trigger the power delivery means at any one of a number of different levels. A touch detector is connected to the power level memory means. Touch detector circuitry alters the power level memory so as to correspondingly alter the power delivered by the power delivery means when the touch detector is touched.
