Want to fit a dimmer switch but new build strange wiring!!


Postby djmarkymark » Tue May 01, 2007 11:36 am

Hi,

I've been a reader of the forum for a few weeks and found it very helpfull. But it's come the time for me to post a question!

I have just moved into a new build and I have a light switch I wish to change to a dimmer switch. One switch controls the downlights, one switch controlls the uplights.

I opened up the switch and saw that they have wired all the neutrals together and seem to just have the live's into the current switch.... so, I can't work out what should be in my new dimmer in the two sets of L1, L2 and C (I think).

Links deleted, no external links allowed.

Anyone know how to connect the new one?

Thanks.[/img]

what you seem to have is feed looped in at switches instead of at light, not uncommon these days.
your original switches where prob 1 ways ie c + L1
so new ones are 2 way, no problem just connect to C & L1 as b4 & ignore L2's. don't touch neutrals at all, regards SPARX

Ok thanks for that. I'll give it a go and report back.
