ABSTRACT:
A current drain reducer for an electronic circuit system such as an electronic amplifier operated through controlling selected circuit branches therein in response to sensing a selected position of a potentiometer used therein. Such circuit branches each has a control conductivity device located therein which has a control therefore connected to a shutdown signal generator which can be a power supply. The potentiometer can have its low terminals in one such circuit branch which may be in a first electronic amplifier circuit and its wiper connected to another such circuit branch which may be in a second electronic amplifier. A sensing circuit for sensing the position of the wiper provides an output signal to the shutdown signal generator.
