Abstract

The present invention lies in the technical sector of industrial systems of connection and refers in particular to an electronic device for the wiring of electronic displays of information transmitted by a transmission circuit device 19 via the closing of a push-button 6 and received via an electrical connection line by a reception circuit device 20, comprising said electronic displays 12, 18, the connection line coinciding with the usual electrical power supply network 8, there being provided a frequency generator 21, in the transmission circuit device 19, able to put out a frequency signal, directly into the network 8, at an established frequency significantly different from the characteristic frequency of the network itself 8, as well as a frequency detector 22, in the reception circuit device 20, able to recognise and interpret, from the network 8, the frequency signal transmitted by the frequency generator 21, to control the display of the information on the electronic displays 12, 18.
