Date Jul. 8, 1993.An electronic device for multiplexing several loads to the terminals of a source of alternating electrical energy. The source(4) of alternating electrical energy is coupled by electromagnetic flux to the loads by using primary excitation windings 71, 81 and 91 connect to the terminals of the source (4) of alternating electrical energy and secondary windings respectively corresponding to the number of loads. The secondary windings are at least partially coupled to the primary winding and are each connected to the terminals of a load. The coupling is inhibited by auxiliary winding 73 which are each totally coupled with the secondary winding 72. The inhibition function is controlled in order to inhibit all the magnetic couplings except for one and this particular one changes as a function of the respective load to be coupled to the source 4 of alternating electrical energy.
