Trouble wiring a double light switch

marbleheadj

Hi,

I've changed all the plug sockets in my living room successfully but I've hit trouble changing the double light switch.

The wiring looked a bit unusual and must have been there since the houses were built, I copied the wiring the best I could but still no light!

The wiring looked like this:

Switch 1: Red wire to L2, Yellow wire to COM
Switch 2: Red wire to L2, Unmarked wire connecting L2 to COM

Like I say I tried copying directly and it didn't work.

Can anyone correct whatever mistake I've made or suggest another solution?

Thanks

you need to explain your lighting system a bit better.
what exactly do the two switches control?

marbleheadj

the two lights in the living room

ormus

normally you would have a red to each com terminal, and the blacks to the L1s.

Unless theres two way switching !

How many wires do you have at the switch ?
And what colours are they ?

Are there any cables in connector blocks at the back of the switch as it seems the live is looped between both switches to feed the lights. I presume each light is separately controlled by by a switch?

Thanks for all the replies so far....

Yes there is a connector block at the back that has two wires going into it on the left hand side, nothing on the right

each switch controls one light

Switch one has a red and yellow wire
Switch two has a red and another small wire that was in the some port as the red and then connected to another port on switch two

Hope thats clarifies it

These could be your Earths...Do these cables at the back connect into a brass lug into the back-box of the switch, or do they go into a plastic connector block?

Do any other switches control the same lights, or is it just one switch per light?

Any chance you can take a photo of the switch connections please?

I can't get the picture attached and it kinda grainy as I have no light!

Thanks for your help
