Dimmers dont work like that, they have electonics, not just a "pot" as your post implies
what room is this to be in?

OOI - why did you think dimmer switches had L1 & L2?
Last one I fitted did, and it was only a couple of weeks ago. Having said that, I did originally plug a low-energy bulb into it and it flickered, which stacks up with the way a Triac-driven dimmer works (see-I've been doing my homework now)...

More research topics for you, if you want to learn some more stuff:
1) what is reverse phase control dimming, and why this can't be done with triacs.
2) the problems caused by the harmonic currents caused by phase control dimming
3) how the analogue (0-10v) stage lighting control system works
@original poster: grid system
So it had a live feed, and two switched outputs - one dimmed and one not dimmed?jtaunton said:
Hi
I do want to separately switch the lights and the extractor.
The switch is outside the room.
I was not sure if
a) A double dimmer switch would power the fan properly, or,
b) it is possible to get a single plate with one switch and one dimmer ?
Thanks

I don't think I've ever seen one, but that doesn't mean they don't exist, but if you can't find one you can assemble one from a grid system, which lets you make up a single plate containing either a mix of different things and/or a large number of things.
You buy individual modules, which can be switches, fuses, dimmers, neon indicators etc, a frame to fix them to, which then screws to a flush or surface mount box (conventional ones for the smaller sizes of frames) and then a plate to cover the whole lot up, e.g :

Exactly that - It wasn't anything special, just the first dimmer switch I picked up at Do-It-All. I originally thought that was what the poster was looking for, but apparently not now the thread has developped.
Never seen one like that. What was the purpose of such a design described as?

Some old MK Logic dimmers had terminals that allowed you to wire two different fittings to the switch so that one was switched and dimmed, and the other just plain on/off.
Maybe Volex, too??
But I don't think either co. makes anything similar now.

Sounds like a Good Idea™ - I'll bet there are quite a few people who'd like to have bathroom lights on a dimmer but retain a fan triggered by them.
