    Firstly, do you have earth wires with a green/yellow sleeve on inside the box in the wall? (Another piccy maybe?)

    You have bought the wrong switch.

    You need a switched fused spur with or without neon, and just copy old to new connections.

    If the new spur is metal it will need to be earthed.

    No.

    What he has now is a 20A DP switch, not a fused switch. I am therefore assuming it is on a 6A lighting circuit, and, whilst the new switch is not 'the same', it will be fine to use, as long as the earths are present(as you say).

    Yea, I think you are correct, but either way the connections are the same.

    Yes, you are correct, but either way the connections are the same.

    And what about the Neutrals?

    OP follow my original advice, but as he has stated you could also use a dp switch with neon.

    Thanks, you swiftly edited that post! :p

    No.

    Tommy,
    You need to join all the blues together in a single connector block, this just gets tucked inside the back box.
    The two browns which are together now, move them both to COM on the new switch.
    The lone brown, put that in L1.
    Move the earths from the back box and connect them all to the earth on the new switch.

    No, it's not bad advice, it's normal looped in at the switch wiring.

    What neon, the new switch doesn't have a neon? The OP chose the switch that he wanted to go on the wall there, not me.

    You did indeed make a small mistake by jumping to an incorrect conclusion.

    However, you then added comments denigrating the advice and posters on the forum, much like the above post, and claiming you were the only one giving correct advice. Unfortunately, for you, you and your advice were wrong.


    Perhaps someone fitted the 20A DP because they wanted the neon or because they just had one. The OP obviously doesn't want a neon, so

    why is a perfectly normal switch, that most people would fit "the wrong switch"?
