They are wired so that operation of either switch will control the light. This is because the terminology used is very different. So for the benefit UK visitors . Three core and earth cable is required to install two or three way switching and this should be run from the first light switch to the second and then wired as shown in this diagram. Switch one is the switch that contains .
Metal switches are connected in exactly the same way, but the earth wires connect to an earth terminal on the switch plate .
Examples of the most commonly used UK lighting circuit diagrams.
The most basic circuit, with only two wires at the switch. This arrangement would typically be used in conduit, and uses two wires between each switch. This is where you can control the same light via two . Two way switches usually have terminals marked COM, Land L2.
Wiring two way switches for lighting. You can check the following points: Are all the wires connected to the switch ? This type of switch is used where two switches control the same light, such as at the . Cable D – Tree core and Earth connecting the two two way light switches. 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.
When the switch is on, both terminals are connected together. Typically, these terminals will be marked COM and L(sometimes Land L2). How to wire the two - way and intermidiate lighting circuit.
Two - way and intermediate lighting circuit wiring (AMExam) - SparkyFacts. Connect the Line wire of this cable to the supply . EU harmonised colours for the supply conductors of twin and earth cable: New colours. Ensure the electricity is isolated . The old colours will cease to be used from.
COM or Common is the terminal to which the live core wire is attached - this is the brown wire (formerly red).
