ABSTRACT:
A touch-actuated electronic switch is disclosed including a direct current or voltage supply having its output or common terminal connected to a voltage source which is alternating with respect to Earth ground, two signal inputs, at least one touch surface, means for connecting the touch surface to one of the signal inputs, an amplifying device and a network for imposing part of the signal found on the signal inputs onto the amplifying device. A mode of operation is disclosed wherein the amplifying device is allowed to float up and down in voltage to follow in part the alternating voltage of the signal inputs. The above arrangement can be used, through the addition of additional circuitry, to switch the power to a load on and off any time the touch surface is first touched.
