    **SUBJECT SHOULD HAVE BEEN CLEARER - TRYING TO REMOVE 1 GANG 2 WAY SO LIGHT ONLY CONTROLLED BY DOUBLE POLE SWITCH**

    Hello,

    I have a Double Pole switch at DOOR 1 controlling two bars of GU10 LED Spots (4 on each bar). One bar is on an independent circuit which is working fine, but the other is also connected to a 1 GANG 2 WAY SWITCH at DOOR 2 which I want to remove. I took the wires off it, but the lamp connected to it using the Double Pole switch will then not light.

    Here’s a wiring overview accounting for the lamp I am trying to resolve the issue with only.

    DOOR 1 (DOUBLE POLE SWITCH)

    N1: Red
    N2: Blue

    DOOR 2 (SWITCH TO BE REMOVED)

    B: Yellow (separate cable)
    B1: Yellow (same cable
    as
    B2)
    B2: Blue (same cable as B1)

    I’ll post a diagram as asked in due course. Thanks in advance.

    You need to disconnect the "strapper" switch (three core and earth) which runs between each switch and controls the two way switching That will leave the two lamps connected leaving the wiring of the live and switched live to be wired up from the existing cables.

    This explains the principles behind two way switching.

    If your wiring is different (and it can be) or if you're uncertain about what to do, it pays to get an electrician in.

    You need a two-way switch for the two-way circuit; not a double-pole one.

    I'm sure you know exactly what you've written but I'll be honest it makes little sense to me.
    Photos of the wiring of both switches please. I know you have already made changes but it's a starting point for us.

    I think you are saying you had a 2 GANG SWITCH at both doors and you now wish to have a SINGLE GANG SWITCH at both doors, one controlling both lights and the other controlling the outside light.

    Thanks for the replies so far. I’ve edited my original post to hopefully make it clearer and will draw a diagram as soon as I can.

    I think the confusing maybe the DOUBLE POLE switch your reffering to.
    Do you mean a 2 gang switch

    Also the N and B1 etc where are them markings

    I'm assuming the 2gang switch is marked A, A1, A2, B, B1, B2 and the 2 pole is marked L1, N1, L2, N2

    That would never have worked as 2 way properly as once the DP switch is off, the 2nd Door switch would be defunct,
    I quess it was used to just turn off the second light whilst the DP switch was on
