Hi I have installed an outside light next to my front door. I have fed the cable to an existing light switch. This switch operates a light at the bottom of the stairs with one switch and the light at the top of the stairs with the other. There is a similar switch at the top of the stairs.
I have purchased a 3 gang(switch) switch plate and need to replace the existing 2 gang(switch) plate. Its the wiring I can't get my head round.
The old switch had two blocks on the back. Each has an L1 & L2 at the bottom and a 1 & 2 at the top. The new switch plate has one single block split into three sections each of which has L1 & L2 at the top and COMMON at the bottom.
The mains cable has Red, Black and Earth, the two other existing cables have Red, Blue Yellow and Earth. My new cable has Blue, Brown and Earth.
Complicated I know. maybe a diagram would help me! the ones with the switch was poor.
