Hi.
I recently moved house and thought I would replace the light switch in one room with a dimmer switch. I have done this in a previous house and it was straightforward so didn't anticipate any problems.
However, when I opened the existing connection - I'm a little confused about the cabling and hoped someone could explain?
I was expecting to see one red wire (L1) and one black wire (L2) which I would just replace into my new dimmer switch.
Instead I see 2 red wires connected. The terminals are labelled "Top" and "1" and "2" and then at the bottom just "1" and "2"
One red cable is connected to "1" at the "Top" and the other red cable is connected to "1" at the bottom.
(There are black cables but these are not terminated on the existing switch. And there is a green/yellow earth at the back)
My confusion is - which red cable do I connect to which terminal on my new dimmer switch?
Can anyone help? (I thought it best not to do anything further until I'd checked with the experts!)
Thanks.
