Manufacturers don’t make decorative one way switches. This is because two way switches can also be used on one way circuits. If you’re circuit is only one way, you can ignore this terminal and it will still work. When you’re wiring decorative light switches such as chrome or stainless steel etc, you’ll find that the switch will also have an L2 terminal which means it’s a two way switch.
The other terminal is marked as L1 and is the output to the light fixture. The common is for the live wire that supplies the input voltage to the switch. If you’re attempting to wire anything more complicated like upgrading a 4 gang light switch to a 4 gang dimmer switch it may be worth taking a quick photo first just in-case you get muddled up with the wires and need to revert back.Ī one way light switch has two terminals which is a common marked as COM or C. These ratings differ with 1 gang, 2 gang and 3 gang versions. LEDs often need to be de-rated, for example the Varilight V-Pro is rated a 120W for LED and 400W for incandescent with a maximum of 10 LEDs. The maximum current rating should also be adhered to this is usually 6 to 10 amps per switch for on/off switches and for dimmer switches its 250W or 400W. Basic safety procedures should always be followed such as switching off the mains supply before commencing any work. We are not electricians and have taken all the diagrams from the instructions that are supplied with the products we sell. Ranging from simple one way switches to more advanced keypads that are used in home automation systems such as Lutron.Īny electrical wiring should be done by a qualified electrician. This FAQ has been produced to explain the different types of light switches, circuits and terminologies that are used in modern day lighting installations.
