DISPOSITIF PERMETTANT DE COMMUTER D'UNE SOURCE ELECTRIQUE A UNE AUTRE

摘要

The present invention relates to a device making it possible to switch from one electric source to another. It comprises two electromechanical relays, each of the two relays being capable of supplying power current coming from one of the two sources. The two relays are connected to one another so that the current supply for controlling one of the relays prevents the current supply for controlling the other relay.
