Hi,

I current have a wall switch (double) with 3core+earth and want to know how to wire them to switch 2 lights on/off independantly.

There is only 1 switch needed.

Please see my diagram for details.



Thanks for you help!

OK, you should have a 2-gang switch. this will have two sets of C, L1 and L2.

Connect the red to both Cs on the switch (link between the two)
Connect the blue wire to one of the L1 terminals
Connect the yellow wire to the other L1 terminal

I guess that the 3-core cable goes to one of the light fittings?
Connect the red from the other end of the cable to the loop terminal (thats your live feed back to the switch.
Connect the blue wire to the L terminal on the light fitting.
That is one light done.
Now you'll need a piece of two core & earth cable to run between the two light fittings. The wires will probably be blue & brown
At the fitting where the 3 core terminates you'll need a small terminal block (choc block) connect the yellow wire from the 3 core to the brown wire on the 2 core cable. Connect the earth wire to earth!
At the second fitting connect the brown wire from the two core&earth cable to the L connection and Connect the earth wire to earth!
Thats the other light done.

Your light bulbs go between N & L at each light fitting.
The blue and yellow wires must be marked with red or brown sleeve or tape to show they are live!
All earth conductors must be sleeved green&yellow.

That's it.

That a great help cheers!

Would you mind checking over my new diagram to see if I undersood?

Also, would I be correct in saying that the new twin&earth joining cable doesn't have the blue wire used?

Cheers

Looks like u got the idea. You didnt redraw the switch though. Per above, you should have a switch plate with two switches on it - two sets of C , L1 & L2 terminals.

also as the two wire cable will be at the lighting rose 2 you could earth that end too (just pop them all into the earth terminal there.
Yes yr right, the blue conductor is not used.

Good luck

ive got the same problem in my front room, but it seems that the lighting circuit starts from one of the lights so ive got two sets of mains wires and two white cables. but at the light switch ive got two white cables and one has yellow blue and red? im not sure where that comes from as its not part of the lighting circuit.

can anyone help me sort this out so that the two switches operate both lights independently,
cheers

You should start your own post not hijack another members.

And try to include diagrams/photos.

It's OK, the post you hijacked was a year old so they won't be too upset. When you do start a new post please do explain exactly what color and how many cables and how many cores in each cable are at each light switch and the fittings. Photos are even better.
