The system comprises a transmitter module which includes a circuit in which an electromagnetic transducer is established which generates a magnetic flow, supplied by means of a control circuit with the aid of a switch or similar element by means of one or more batteries, said magnetic flow is received by an electromagnetic transducer established in the receiver module, so that the magnetic flow induces an electrical current which supplies a control circuit through which the power load in question is supplied. In this way a receiver module is obtained, associated with a power load which does not need a source of supply, and which remains inoperable until it is activated by means of the transmitter module and which does not require any type of maintenance. Both the control circuit of the transmitter module and the receiver module may have the means to codify/decode the signals in case should the system application require a high degree of security.
