House Electrical Advise Please
Can anyone help, I've replaced the lights in one of my bedrooms, and wanted to change the switch, I took the old one off and replaced it with a new one and found some interesting results. Firstly there are THREE RED wires goimg to the switch, two in in one side (same contact point) and one the other.
Take the first as wire ONE Take the Second as Wire TWO Take the thrid as Wire THREE. Leaving the switch removed and all 3 unconnected means the light is OFF AS ARE ALL THE REST OF THE UPSTAIRS LIGHTS! wire ONE and TWO together means the light in the room is ON (always) and I can switch the rest of the upstairs on and off wire ONE and THREE together means the light in the room is ON (always) and I can switch the rest of the upstairs on and off wire THREE and TWO together means all the lights are OFF, nothing switches ON What have I done wrong ?? Any help is gratfully recieved |

Wire it up in the new switch exactly the way you found it in the old switch!
Clearly the two wires that share one pole are what continues live on for the rest of the lights upstairs so they must remain sharing one pole of the switch (normally this occurs in the ceiling rose not the switch). The wire on its own goes to the bedroom light. |
So, when you say you're putting wires 1&2, 2&3 and 1&3 together, you're obviously putting the remaining wire in the other contact point?

His test doesn't quite make sense though.
If you took turns connecting just two wires together (leave the remaining one) the three combinations should be:- 1) Bedroom light always on, rest of upstairs always off 2) Bedroom light always off, rest of upstairs works fine 3) Nothing works Using these examples: The common wire used in both 1) and 2) is your Live The other wire used in 1) is to the bedroom light The remaining wire continues power to the rest of upstairs You need to do it two wires at a time because if you connect the remaining wire to the other side of the switch then depending whether the switch is on or off will affect the result! |
thanks all for the replies, cracked it today, .....:)
Wire 1 was the always on live feed Wire 3 was the one leading to the bedroom light Wire 2 was the lead to the rest of the upstairs...........but was connected to Wire 1 and 3 in the light fitting I put up earlier :eek: The Answer :- Wire 1 and 2 together on one side of the switch with Wire 3 the onther side. Wire 3 to the light fitting Other 2 wire in the fitting join together :) Only took 2 hours today and the use of my PC Based DMM ;) |
