    hi,

    I know this is probably old ground but I'm having trouble comparing the wiring diagrams I am finding online with what I can see inside my switches so hopefully someone can point me in the right direction.

    I have a current twin light switch and I want to remove one of the lights completely and hence replace with a single switch - so what I look inside the current switch I see this
    and the new switch looks like this
    (the former is dropped out of the current mount so upside down compared to the new one).

    I am concluding that the blue and yellow wires are the ones I can see in the light fitting I want to keep but I don't know what connects to where on the new switch - not sure I want to trial and error wrongly with my electrics.

    The new switch is an MK but the instructions aren't labelled like the switch so before I start experimenting i thought it worth asking for pointers.

    Any help much appreciated.

    Thanks

    Your new switch is an 'intermediate' used in the central position of three switches when all are used for the same light such as a stairwell.

    No matter it can still be used (just more expensive).


    You need the red (discard the link) in '1' (doesn't matter which) and either the blue OR yellow, whichever works the light you are keeping, in the other '1'.
    Terminate the unused wire in a connector block and position safely.


    More importantly, what will happen to the wires at the light you are removing?
    Please post a picture of the wires at this light and we may be able to see how to make them safe.
