    Hi,
    I am changing a plastic light switch for a new metal one.
    The old switch has two red wires, which I assume connects to the lamps above the bed on the same wall as the switch.

    Could you advise me if I leave the earth wire attached to the metal box, or do I attach it to the new switch’s earthing point.

    Thanks

    Attach the earth to the earth terminal on the switch, then run a link from the switch to the back box.

    Leave the earth wire where it is and take a link from the back box to the metal switch.

    The advice you've been given by @arrow is incorrect, the earth should attach to the box with a short lead to the switchplate

    What do you mean by "wrong once again" and that "I keep giving out wrong advice"

    I can't really be bothered to go looking, but one example is conduit is 1/2" barrel another would be,there are not houses tubed in solid conduit. There are lots but I would need to search.

    Post 5 is correct in my opinion.

    Would you terminate the earth wires for a socket in the back box first whether plastic or metal? I very much doubt it, you will take them to the socket first, which is correct. That is why it is correct to go to light switch first.

    Good point but I've never done it your way, my reasoning is that you could have 4,5,6 earths I'd rather them be connected to a point that doesn't move.

    Are those plastic lugs in that back box, behind the Sellotape?
