<p>An electrical control and connection system in which besides Line Neutral and Earth conductors (L, N, E) there are at least two additional conductors (SL and 2W) which are provided for control purposes; one of the additional conductors (SL) is provided with a switch (7) permanently provided between outlet points (5, 5', 5'...); the switch is operated by insertion of one of at least two possible different styles (A) of connector whilst at least one other style (C) of connector leaves the switch mechanism unoperated. The switch may also be operated by a dummy connector. The system provides improved flexibility in installation without apparent complexity for the installer.</p> |
