I have 2 lights, controlled by 3 switches. I am trying to replace one of the standard switches with a dimmer. I have selected the one I want to change and taken the cover off. At the back of the switch there are two holes at the top labelled L1 and two at the bottom labelled L2. A red and yellow wire go into the top 2 and a red and yellow wire going into the bottom 2. There is also a blue wire that enters the metal box behind, which is not linked at all to the switch, it just comes out of the wall and then goes back in. Finally there is a green/yellow wire which earths the metal box.
The new dimmer switch (plastic) has three holes marked, L1 L2 and Com.
Help, How do I wire this?
I have tried linking the yellow and red wires marked L1 and the yellow and red wires marked L2 and putting them in the respective holes in the new dimmer switch, leaving the com hole blank. nothing happened.
Thanks in advance for any help.
