Hope someone can help, apologies I’m new to this. I have a two gang switch for ceiling lights (work perfectly) which I am turning into a three gang in order to add a wall light. I have successfully connected the new three gang for the ceiling lights. As I’m unable to take a spur from the existing N in the ceiling I would like to add a strapper in the switch for the wall light but confused by all the diagrams on line. I have linked up the L and the Spurs in yellow for the ceiling lights are from L1 on the two switches. Appreciate any help!
