Help replacing dimmer switch

[technics2001]

Apologies for posting another switch wiring query but I can't find an answer anywhere.

I'd like to replace a dimmer switch with a standard switch so that I can use energy saving bulbs.

The dimmer has 2 x brown live wires connected to two different terminals, both marked L2 which are the only terminals on the switch. There is also a blue neutral wire in the socket but not connected to the switch itself.

The new switch has Com, L1 and L2 terminals - should I just connect the brown wires to L2 and leave the neutral wire loose as it is at the moment?

Thanks in advance,

Craig.

One brown wire will be the feed which goes into C and the other brown wire will be the switch wire which goes into L1 thats how i see it.whats the blue wire doing is it in a connector block?

Where and how is blue connected?
If you look at he cable brown, brown, blue are they within grey PVC sheaths and if so are they paired up or single?
Is there an earth (CPC) cable?
Firstly you need to know which one of the brown cables is offering the live feed to the switch.
You will need either a voltage tester or a multi-meter for this, once you have found this, that cable will be connected at your com terminal.
and the other brown cable to your L1 or L2 terminal.

Yes, the blue wire is in a connector block.

How would I know which brown wire was which? Or does it not matter?

Sorry, you posted while I was replying to the other post.

I'm not at home now but I'm pretty sure all the wires come out of 1 grey sheath. There is an earth cable aswell which is also attached to a connector block.

So I will use the multi-meter to find the live cable and attach that to Com, and the other to L1?

yeah use the tester to check which one is the feed which goes into C common,is the back box metal or plastic?

Remember to switch the power off once you have found out which one is the feed.

Thanks all, I'll try again tonight.

The back box is plastic.
