He's managed to rip a light switch clean off the wall. The switch is for two wall up-lighters and the original wiring was a mess when I found it.
Currently I have three two-core cables at the switch - all are colour coded blue and brown for neutral and live which I think is non- standard. Anyway, two of the cables go to the first light (the terminal block behind the light has two live wires and two neutral wires going into it.) The second (furthest away) light only has one live and one neutral cable going to it.
I bought a new light switch. It's the only switch for the lights and the terminals on the switch are marked L1, L2 and Common.
I think that I need to put the feed live (from the mains) into the Common terminal. I think I then put the live wires from the other two cables into the L1 terminal on the switch and connect the neutral wires together in a terminal block so that they are unbroken from the mains. Is this correct? How do I know which live cable should go to Common as there is no black sheathed cable - only three brown cables to choose from?
I know that I should call an electrician etc. but the nearest sparky is 100 miles away and this should really be a simple job. Any advice on what to do would be much appreciated.
