Abstract

Afin de simplifier une installation électrique où les récepteurs et interrupteurs sont reliés à une même ligne d'alimentation à deux brins via des contacts au moyen d'une commande multiplex associée, l'invention propose de raccorder les organes de manoeuvre (9, 95) à la ligne d'alimentation (1) et de relier les récepteurs et interrupteurs à la ligne d'alimentation (1) via des lignes de dérivation (5). Les lignes de dérivation se terminent par des connecteurs (6). L'invention prévoit également des raccords par déplacement d'isolation (9) pour assurer le raccordement électrique des récepteurs et interrupteurs à la ligne d'alimentation (1) via des lignes de dérivation (5). Chacun de ces raccords est doté d'un élément de communication (95), d'un organe de manoeuvre (95), de l'élément de commutation (96) et d'un dispositif de surveillance du courant (A).
