Abstract
The present invention relates to a switching device for selecting a voltage between an a.c. voltage and a d.c. voltage using the ground as a reference, meant to be controlled by a two-state signal, using the ground as a reference and of the same sign as the d.c. voltage, including means for adjusting the turn-on time of a switch in the selection of the d.c. voltage.
