I'm wanting to replace an old 2 way switching light system with a single one in our front room as I've filled in one of the doors. I can't make sense of the old light switches though - I can't even work out which is the master.....
Switch one
Common has both yellow and red, L1 has blue
Switch two
Common has blue, L1 has red
This lot all feeds back to a junction box somewhere or other in the floorboards which I really really don't want to try to track back to.
Can someone tell me which wire is which? Final aim is to remove switch two as it isn't needed - but I can't even work out which is the old master switch.
