One way lighting circuit

Wiring details for one way lighting circuits as used in the UK. These diagrams show various methods of one , two and multiple way switching. Switches are shown as dotted rectangles. This FAQ has been written to explain the different types of light switches, circuits and terminologies that are used in modern day lighting installations.

Ranging from simple one way switches to more advanced keypads that are used in home automation systems such as Lutron.

Any electrical wiring should be done by a .

All work carried out should comply with all applicable Wiring Regulations.

Read the instructions carefully before commencing . When the switch is on, both terminals are connected together. Typically, these terminals will be marked COM. They are wired so that operation of either. This is where you can control the same light via two . It shows the connections between supply from mains to ceiling rose, light bulb and light swit.

I have one switch to control one light. While this diagram describes the circuit in . Be cautious when opening up multi- way switches. The lights they control should take power from the same circuit , but if yours are incorrectly wired and take power from different circuits , there will be live cables at each switch position when one circuit is isolated.

There is more than one method of wiring multi- way lights. A piece of brown sleeving is used on the blue wire, as both wires are live. The diagram belove shows the new colour codes. In this state the lamp is off, changing the position of either switch will switch the live to the lamp turning it on. Two way switching means having two or more switches in different locations to control one lamp.

If you now change the position of the other switch the circuit is broken once again. Note that Land Lare never connected together. Again, some makes of switch may have alternative markings such as LLand L3. The common is the main live coming in.

One way switch (UK light switch). The Lis the switched live going out to the light.
