摘要：The electronic switching device serves to control the connection of a load to avoltage source by a switch which is controlled in a first operating mode directly by abinary signal furnished by a signal processing circuit and in a second operating modeinverted. The switching device has three terminals, of which the first permanently remainsconnected to a first terminal of the voltage source and to a first terminal of the load,whilst of the other two switching device terminals the one is connected to the secondterminal of the voltage source and the other to the second terminal of the load. Theswitching device is configured so that it can be changed over from the one operatingmode into the other by interchanging the connections between these two otherswitching device terminals and the second terminals of the voltage source and of theload, respectively.
