Light Switch Wiring Diagrams for Troubleshooting
- One light switch contains a 3-core & earth cable. The other light switch contains one 3-core & earth cable and one cable which has 2 browns and 1 earth (is this called 2-core & earth?). I have two identical switches (1 gang, 2 way) which have one set of C, L1 and L2 in each switch.
- I have wired the lights as follows:
- Light switch one – C = brown, L1 = grey, L2 = black (earth to earth terminal in box)
- Light switch two – C = brown (from 3-core & earth cable), L1 = brown (from 2-core & earth cable) & black, L2 = brown (from 2-core & earth cable) & grey (earth to earth terminal in box).
- The light is on but the switches aren’t working as they should. Can you please tell me where I’m going wrong?
Many thanks.
