    Metal box with metal light switch
    Hi
    I am replacing plastic light switches for chrome switches. The back boxes are metal and are earthed with the single earth from the main supply. Do I just need to run another single length of earth from the earth terminal on the box to the earth terminal on the switch?

    If so, what wire... 1.5mm OK? Does it matter?

    Thanks
