Unbelievable Fitting A 2 Way Light Switch
Hold the red and black terminals of your circuit tester to a red and a black wire that appear in the same cable.
Fitting a 2 way light 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. Then turn on the light switch with all power off to the lighting circuits there is no power to the switch. One thing to remember is that the wiriing on light switches is only switching the live wires not the neutral if you see black wires or blue wires attched to the switches these are not neutrals.
On the whole 2 or 3 gang switches will always be 2 way switches. Connect the new socket or switch as shown in the appropriate wiring diagram in these fitting instructions taking care that only the copper conductor s enter the terminals. This indicates that they can be live.
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. If you need to control the lights from three places say you have 3 entrances to a large room and need a light switch next to each one you will need an intermediate switch. Using the diagram above this would mean either cable 1 2 or 3.
Those wires have just been used for convenience. Each two way switch will have three terminals arranged as a single and a pair. When using multicoloured stranded cables make sure that after the terminals have been tightened no stray strands are left.
This can be confusing. A common c l1 and l2. If done properly they.
Woodie s will show you how to replace a two gang switch. This cable needs routing via the easiest route here are the guidelines and permissible zones permitted wiring zones. If you are buying switches and don t know exactly what you need then it is often a good idea to get a 2 way switch anyway.
