Wire a 3 Way Switch
Induction loops and RF interference
Three-way switches control lights and receptacles from two points: for example, a light in a hallway that can be operated from the first floor and second floor. It should also help in understanding the functions of each type of switch. When wiring a 2-way switch circuit, all you're really doing is controlling the power flow ( Switching off/on) to the load (a light, lamp, outlet, ceiling fan etc..). Now a typical circuit will contain a 3-wire cable known as romex. The cable consist of a black wire. 2 way switching means having two or more switches in different locations to control one lamp. They are wired so that operation of either switch will control the light. This arrangement is often found in stairways, with one switch upstairs and one switch downstairs or in long hallways with a switch at either end. Here we have a.
All electrical pages are for information only! Two way switching is not as difficult as it first seems and should be pretty straight forwards if you follow the diagrams below.
If the switch is in the "down" position it exits the switch on the red wire, entering the second switch at a traveler terminal.

Where is your neutral coming from?
Earth wires have been omitted from all photo's and diagrams for clarity, but must be connected at all earth terminals. Two-way light switches are required for two way switching, these can be identified by looking at the terminals on the back 2 Way Light Switch Hook Up the switch. There will be a Com article source terminal a L1 terminal and a L2 terminal.
This diagram represents a two way switching arrangement. There are other ways of wiring a two way lighting circuit, but this is by far the most common and easiest method. The old wiring colours that are present in the majority of homes in the uk have been used for this diagram. Three core and earth cable is required to install two or three way 2 Way Light Switch Hook Up 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 the live wire and switched live wire. The diagram shows single colours only. In real life these wires would be covered by an outer protective sheath and would include a bare earth wire and would be called a cable.
Red sleeving or tape would of been placed on the wires as shown to show that they would be live at some point. Now this sleeving would be brown. The connections are very simple and there is another guide further down this page. This is the same diagram as above, but using the new harmonised colours.
An inherited renter who said he was an electrician lived in the unit in I acquired the condo inand rented it out untilwhen I moved in. Normally the ground screw goes down, toward the floor, but it can be inserted in the up position with 3 way and 4 way switches. Frankly, I doubt if they will act anyway even if they did receive such a letter. He said he installed the track lighting in the living room different circuit which was different from the lighting fixture that was installed when I lived in that unit before from to
Brown sleeving or tape would of been placed on the wires as shown to show that they would be live at some point. Here you can see the back of a light switch, in this instance it is a two way switch being used for a one way light.
A visit web page way switch has only a common 2 Way Light Switch Hook Up L1 terminal and a two way switch has a common, L1 and L2 terminal, like this one in the picture.
Note that new harmonised cable is being used Brown and Blue and note that Brown sleeving has been placed over the Blue wire, This signifies that it will be live at some point! The earth wire should always be connected to the earthing terminals, it has been removed for clarity here but must be connected, even on plastic light switches, unless there is no earthing terminal. The back box will need earthing unless it is plastic and there is no earthing point.
For two way switching you need a length of three core and earth cable long enough to reach from the existing light switch to the place where you intend placing the second light switch. This cable needs routing via the easiest route, here are the guidelines and permissible zones permitted wiring zones.
This is not the new harmonised cable so the colours may need changing, the earth sleeving still needs using before connection as with all cable.
There are no set rules for which wire does what in three way lighting, but I am going to use the most sensible option.
There are no fixed regulations for which wire goes where but if you follow the colours that I have used here, they seem to make sense! Note how all of the wires have brown sleeving on them! I have slid this back a little then you can see the actual colours of the wires.
How to wire a two way light
The brown wire and the blue wire that is sheathed brown are already in terminals L1 and L2, this is described above.
These two wires are the Permanent live and switched live. The Yellow wire goes in the common terminal, Red in the L1 terminal and Blue goes in the L2 terminal. The Grey wire goes in the common terminal, Brown in the L1 terminal and Black goes in the L2 terminal.
When ever you fasten a wire into a terminal, always give it a gentle pull to ensure it is fastened correctly. This can save hours of work later on when the wire pops out and stops working!
Two way light switching | Light fitting
This is the back of the click here switch that will make the circuit 2 way, once again the brown sleeving has been slid back for clarity. The wires in this switch should mimic exactly the three wires that you have put in the other switch. You now have a light that can be switched on or off from 2 different locations.
How to wire a two way light switch video. Two way light switching. Here are step by step instructions on how to wire up a two way lighting circuit or to change a existing one way light switch to a two way system, this is very useful on stairs etc.
2 way switch (3 wire system, new harmonised cable colours)
Building regulations are changing all the time read article modifying your home electrics could be against new rules and could invalidate 2 Way Light Switch Hook Up home insurance, if in doubt check first!
This cable needs routing via the easiest route, here are the guidelines and permissible zones permitted wiring zones This is not the new harmonised cable so the colours may need changing, the earth sleeving still needs using before connection as with all cable. Remove the wire which is in the common terminal and place it in the L2 terminal. These two wires are the permanent live and switched live wires.
Navigation You are here: Home Light fitting Two way light switching. Before working on any electrical circuit you must ensure that it is isolated correctly and cannot accidentally be switched back on.
