    Hi - I'm hoping this is fairly simple but I have cable in the garage which comes out of the rose in the picture and runs along out of the door to a PIR light. I would like to add a switch though.

    Am I right in thinking I need the cable to go into the switch and wire the live into a terminal. And then have another cable with the live into the other terminal and splice the neutrals together.

    a) is this OK?
    b) what should I do about earth? The switch and back box is plastic but the light is metal
    c) for my new cable to run from the switch to the light - what should I use?

    Any advice would be great.

    Add another cable to the junction box and run that to the switch.

    It will require some alteration to the wiring in the box.

    My X-ray specs need new batteries. Take a pic of the wiring inside the JB.

    Thanks Winston1.

    EFLImpudence, I was going to use the existing cable which runs from the junction box to the light. Ie Wire it into the switch and then run a cable out of the switch to the light. I didn't fancy fiddling around with the junction box.
