Hoping for some help I am fitting a new double light switch were one of the switches is a 2 way light.
The back of the light switch looks like this
C C L1 L2 L1 L2
Now the problem I have is that I only have four wires and six connections. All of the wires are red but two of them have a extre grey sleeve ( I assumed these were the common wires).
I have tried wiring in the two commons then wiring switch one L1 connection and switch 2s L2 connection then bridging the L2 on switch one and L1 on switch two, I can get the two switches to work this way but only if the partner switch to the 2 way light is left on.
Where have I went wrong???
