ABSTRACT:
An electronic switch of the type having two external lines, one of which is connected to one pole of an operating voltage source in series with a load and the other of which is connected with the load. The switch comprises a sensor, e.g. an oscillator, responsive to proximity of an object thereto and has an output transistor operated by the sensor with blocking and conductive states selectively controlled by the transistor in response to the oscillator. A MOS-FET power transistor is in series with the output transistor and, to reduce the voltage drop in a conducting state of the electronic switch, a self-conducting MOS-FET is used as the MOS-FET power transistor.
