    1st time on here
    I am changing a 2 gang lightswitch on my top landing that controls top landing light and the one on the floor below
    The old switch is wired as follows
    Blue wire with red sleeve to L2 top
    Red wire to L3 top
    Yellow wire with red sleeve to L1 bottom
    Yellow with red sleeve to L1 top
    2 red wires to L3 bottom
    Black and blue wire to L2 bottom

    New switch has the following

    Top - comm , L2 , L1
    Bottom L2 , L1 and comm

    Can someone advise me what wires should go where

    Thanks very much

    You are misunderstanding how the switches are laid out. Please post photos of the wiring side of:
    1. The existing switch before you disconnect anything
    2. The new switch

    2way switching gets DIYers every time , especially when the orientation of the new switch terminals is slightly different....

    Even as a time served sparks I am very careful to identify the cores when I remove a switch just incase I get sidetracked

    My favorite is when a light fitting is replaced..
    “I put all the reds together and all the blacks and it just went bang”

    Or "now my light won't go off" or "the light I fitted works fine but now the living room and kitchen lights don't work"
