Here is my dilema, I have a 2 gang 2 way switch call this (switch A), 1 controlling the ceiling light - no problem, on the second switch of the 2 gang 2 way I have 2 x 4 core cables one going to a switch one side of the bed and another switch the other side call these (switch B and C), these switches are for wall lights above the bed. (On the Switch B) 1gang 2 way I have a 4 core and the switch wire, and on the other 1 gang 2way (Switch C) I have just a 4 core. My problem is when I have all the switches connected, eg I switch A the bed lights come on I go to switch B to switch off nothing happens until I switch A off and now when I press switch B it works??? Now if I disconnect switch C and put the wires in connector block. I switch A and the lights come on and I switch B and the lights switch off. Now I am banging my head aginst the wall. If you understand what I have written and can help it would be greatly appreciated.
