Abstract

A circuit for switching electrical winding taps (3, 4) which are seats of electromotive forces comprising impedances (8) of transition on passing from one tap to the next. The circuit of the impedance (8) of transition comprises an inverter (9) for connecting the impedance of transition to one (3) or the other tap (4), so as to permit the switching circuit to operate in one direction or the other. It applies to on-load tap changers and to load selector switches for stepped electric transformers.
