    I am trying to change a old light switch to a new one but am at a loss because of the colouring of the wiring one wire is red and one is also red but together with a brown wire I included pictures! My new light switch has l1 l2 and m and a picture not sure what to do if you could help I would be grateful
  2. m is the common, L1 and L2 are the two "poles". For a standard light/switch use L1 and m, L2 is used for 2 way switching.

    Sorry so which wire goes in the l1 and m ? Red and brown one which is at the moment twisted together and the red one on its own ? Thanks Kim

  6. Are you sure you're up to this job? Electricity can kill.

    Look at how the old switched is wired, I would guess from the photo that the brown and red wires are connected to the common and the other sole red cable is connected to L1.
