In the process of replacing a 2 gang switch with a 2 gang dimmer except somehow wrongly labelled wires up when disconnecting old switch and can not get dimmer to work.
The 2 switches operate two different lights however there is only one mains cable into the switch containing 4 wires; red, black, yellow and earth wires. Dimmer has C,L1 and L2 terminals on both switches.
Which wire do I need to connect to which terminal on the switch?
