Trying to install a double dimmer switch

[Leandra]

Afternoon, I'm trying to install a double dimmer switch from a regular double light switch. However, the wiring behind my switch is nothing like that on the instructions.

Any ideas please?

That's perfectly standard wiring:

The only difference with yours is that it's the last switch on that run - there is no outgoing cable with a supply to the next one.

But the connections to the switch itself would be the same if the circuit looped through the lights, as used to be traditional, rather than through the switches.

What do your instructions show?


Also, please, please take a bit of time to learn how lighting circuits are wired and how they work, so that you come to understand what you are doing when you fiddle with them. Genuine understanding is what is needed, not attempting to blindly follow instructions to put-this-wire-in-that-hole without actually knowing why.

Great thanks, the last one I did was exactly the same so really simple. I think I'll leave this one for my Electrician brother to do for me. Thanks for the advice!

Get him to explain to you how it works.
