Abstract

Interphone switchboard, particularly for linking between the door and apartments of a building, characterized by the fact that each user device is linked to the switchboard by a single driver and other common drivers through which the audio circuit is closed and the signaling circuits, and by the fact that each of said own conductors is switchable by means of a switch of the switchboard, selectively, to the microphonic circuit of the same, to allow communication, or to an alternative voltage source to transmit to the handset of user a busy signal.
