Switches




Disconnecting switches are designed to automatically disconnect inside wiring from the mains supply in lighting fixtures. This allows quick and safe maintenance of the installed fixture. They are made up of a female terminal strip (plug), fed by the mains supply and fitted to the fixed part of the fixture, and a male terminal strip (socket) fitted to the opening side. The internal wiring is generally a derivation of the female terminal strip which is always equipped with suitable terminals. The customers can choose to have the connection terminals also on the male terminal strip, if required. When the fixture is opened for cleaning purposes, the switch disconnector automatically cuts off the mains supply, even when the operator has not opened the circuit.

Switches with quick connection





Besides acting as an automatic switch disconnector as described above, the connector on the inside wiring side via the plug/socket system allows the electrical appliance to be replaced quickly when required without the need for any tools. They are available by shunting from either the female or the male terminal strip.
