Are you trying to get a light to work with two normal dimmer switches? If so then it doesn't work! A normal 2 way dimmer is intended for use with a normal switch. You can buy master slave dimmer arrangements but am not sure if they will work with your current wiring setup.

You also need to sleeve the earth wire with green/yellow, I can't tell if the earth is connected in the second pic but it should be.

You sure the bulbs/illuminaires you've got fitted are dimmable?

Are they energy saving?

Are you trying to get a light to work with two normal dimmer switches? .

No - he's trying to get 2 dimmer switches to work with the input to one coming from the output of the other.

That's why he said "One light worked, the other only half did and required the other to be fully on before it could get to half power", and if you look at the photos you can see the two COMs connected together but not to anything else.

(also, I was under the impression that usually there were only 3 wires from a cable, but we have 4; red, yellow, blue and the earth)

3-core & earth cable.



Most commonly found linking 2-way switches - read the article here: http://www.diynot.com/wiki/electrics:two-way-lighting.

But can be used to take permanent live to a 2-gang switch and 2 switched lives away.

And i have just realised that yes, it's only one set of wiring isnt it, so how could the two lights be controlled seperatly, thats not possible it it?

Perfectly possible - permanent live + 2 switched lives - only 3 cores needed.

Unfortunately your switch was wired by an idiot, which is why it doesn't work.

You'll need to trace the wiring and use a multimeter to confirm what's connected to what.

I'm still a bit conused about the 4 wires though; live, neutral, earth and ??

NO.

There is no neutral there. If you put live and neutral into a switch, what do you think will happen when it's turned on?

Please spend some time learning how lighting circuits work before fiddling with them.

I don't suppose that you thought to make a note of where the wires went on the old switch(es)??

 

[ban-all-sheds]

As the OP doesn't think it's possible to have 2 lights independently controlled by a 2-gang switch if there's only one cable, I assumed that he didn't try to do it, and is just an innocent victim of the previous occupant's incompetence.

If it was me, and if I couldn't be bothered to trace which wires go where...
I'd move the red wire. Put it in the same hole with the blue wire which links the two switches.

But which light works? and which of the two switches work?
And which switch is what light?

Turn off powerractice safe isolation.

Remove all conductors from switch.

With terminal block, connect red and yellow. Put terminal block on blue.

Switch on: what happens?
