I'm replacing a broken two gang, one way, dimmer switch with another 2 gang dimmer, . Stupidly I didn't not make a note of where the wires were attached to and am now having problems getting the lights to work properly. One switch does two rows of lights and the other one row of lights. There is one cable in the wall with a light brown, dark brown, blue and earth wire. on the old switch there was a link wire connecting two terminals(can't remember which) I have wired the switch in various ways the best I can do to get all lights working is:-
Switch 1. C light brown, L1 blue, L2 unused Link wire to from L1 to L1 of switch 2
Switch 2. C dark Brown, L1 link from L1 switch 1, L2 unused.
This way switch 1 works , switch 2 only works if switch 1 is on.
If I put the link wire from C switch 1 to L1 switch 2
So
Switch 1. C light brown, L1 blue, L2 unused, Link wire from C to L1 of switch 2
Switch 2. C dark Brown, L1 link from C switch 1, L2 unused.
This way switch 2 works , switch 1 only works if switch 2 is on.
Diagram below may help
Switch 1. C light brown, L1 blue, L2 unused Link wire to from L1 to L1 of switch 2
Switch 2. C dark Brown, L1 link from L1 switch 1, L2 unused.
This way switch 1 works , switch 2 only works if switch 1 is on.
If I put the link wire from C switch 1 to L1 switch 2
So
Switch 1. C light brown, L1 blue, L2 unused, Link wire from C to L1 of switch 2
Switch 2. C dark Brown, L1 link from C switch 1, L2 unused.
This way switch 2 works , switch 1 only works if switch 2 is on.
