How do I fit a double dimmer switch?

my replacement switch doesn't show a C like you say it only shows L so how am I to know where C is.

Attempting repairs can be dangerous....that said !
Are you are replacing a double switch with a double dimmer switch ? If you are then you should have a minimum of three wires at the switch point ,one (live phase)to go to C on one switch, one to go to L1 on switch 1 and one to go to L1 on switch 2. The C on one switch should also be looped to the C on the other . From your discription it looks like the two reds connected together are connecting a live to another lighting circuit.
Stay safe and do not work on a "live" circuit...

Attempting repairs can be dangerous.
In many instances work should only be undertaken by a qualified professional.

I am a qualified electrician and can be contacted on 07747 571292 Warwickshire.

Have you blown up your fuseboard yet? If you carry on you will. Your home insurance will not pay out if you burn your house down and you sound as though you are well on the way to doing that.

Dont risk it!
