I had a 1 gang switch that controlled 3 wall lights & a ceiling light in a bedroom.
I specified the design when barn converted so know there should be 2 circuits, I saw 1 wire out of wall for 3rd wall light & 2 wires for each of 1st & second & 1 wire from ceiling for centre light.
I switched off at mains which said all 3 beds & bath & as expected they all stopped working
Inside the switch box I have 4 cables, each has earth, blue & brown, all 4 blue wires were connected together, 2 browns went to top of switch & 2 to bottom, earths together & to switch.
I removed old 1 gang & got out 2 gang (which could be 2 way but I don't need that facility) and attached earths as they were to the switch.
The diag with new switch was for 2 way which wasn't helpful.
So I split browns & fastened 1 to top (L) and one to bottom (L1) of left gang & split blues to connect the matching pair together, so using all wires from 2 of the cables in. Left others unconnected & switched on - brill - wall lights went on and off as expected but ceiling stayed off.
So repeated pattern to L & L1 on right gang but no joy. Also tried each spare wire in turn wiring like 1 gang diag with brown at top (L) and blue at bottom (L1) - still no joy.
Now I find that whatever I do or don't do with the other 2 cables when I turn the power back on the lights in the other bedrooms don't work either!
Why would the power for other bedrooms be affected by the switch in this one???
(I did swap a switch some time ago in another room, 2 gang for 2 gang & there was a short wire connecting the 2 gangs directly so have tried this L to L too but makes no difference)
Anyone tell me what's going on?? Thanks.
