I am changing a 2 gang light switch. the exisitng wiring has 2 red workes and one each of blue, black and yellow. can you gtell me what wires got to where on the new fitting - L1, L2, common etc
the red and black wire of the two core cable go into r1 and r2 . the three core cable should correspond to the other two way switch that operates the same light make sure you turn off the main electric supply before carrying out any of the work.
