    VB1: Light switch help. DIY stuff. How do I wire this?

    Banned
    Woo a VB1 Help thread.

    I'm replacing a bathroom light switch, cord type thing. The original switch is knackered and very old.

    In the ceiling there are 3 wires - earth, which is sorted, then a thick red wire, and a thinner red wire.

    I think its off the ring here, and the thin wire goes to the light bulb, but i dunno.

    Anyway, on the new switch I got I have SUPPLY L and SUPPLY N, and also LOAD L and LOAD N.

    I realised at this point I have bought the wrong switch (DPST), and its a little bit overkill, but if I'm correct, this should still work as straightforward switch right?

    Can anyone tell me for sure which of the 4 terminals should connect to which wire?

    Thanks

    supply is the power, load is the bulb.
    L and N is live and neutral

    so thick wire to SUPPLY L and thin to LOAD N?

    Thick red to Supply L
    Thin red to load L.

    You have a double pole isolating switch the current requirement to isolate both live and neutral within a bathroom area.

    So basically the wiring is crap, but itll still work as good/safe as the original switch?

    How bad is it that the neutral isn't done?

    Try all the wires together like homer.

    the N is for the blue wires if you have them. (brown[live], blue [neutral], green [ground])

    Thanks people I will try and not die in a bit. Thanks for the help, rep coming your way.

    Don't do the electrics bit until you've checked whether the cord itself has a sort of replacement widget near the top, so you can just replace the cord.!!!

    Hmmmm, two hours should have been plenty of time to change the switch.
    Perhaps we were all wrong and he's fried himself.

    Ooooops. :giggle:

    Wagwan bredda VB1 needs your skills
    So his family he doesn't electro-kills

    His room is dark, there is no light
    Internet fatties, please put this right

    Where does the scary, live wire go?
    Type faster fatty, he needs to know

    Make sure you're honest and tell him right
    Or VB1 will be killed by his light

    Careful Vee Bee, when you flick that switch
    Because 240 volts can hurt like a bitc....
