Re wire light switch?? lost picture!

And how would I use such a device like how would I know what goes where from using such meter

You do need a multimeter first (£6 from Maplins, etc).

On 230v range, one lead on the earth connection and test each of the other wires. Hopefully only one will show up as live (230v). You need to connect up all of the COM terminals to this live feed.

The remainder will be the feeds to the various lights. Connect the remaining (wires one at a time ) to the live feed. Turn the power off each time for safety.
You can then identify which is which of the switched lives. These will connect to the L1 terminals of each switch.

Earth goes to the back box and the switch panel if its a metal one.

Note. I know its not finished, but, uncross those cables so they go straight into the box and fit rubber grommets in the holes of the box to protect the cable sheaths.

OP if you can't get your head round the isntructions already posted, then the problem is beyond you.

As mentioned by doing the above you will initially end up with the correct wiring, but potentially the sequence of switching wrong. So all lights work, but switch 1 might control light 2, whereas you'd likely want switch 1 light 1, switch 2 light 2.

At that stage simply noting which switch is wrong means you just swap the L1 to the correct switch terminal.

Note- isolate each time, and you must ID the live in to the box.

Lets suppose that you decided to take apart your car's engine.
You took pictures of some of the bits but lost the photos. (unlikely, but it can happen).
You have a feeling that you are going to need some proper car repair tools to get the thing back together, but you don't have (or even know how to use) a torque wrench, a gear puller, etc.

You ask on the Internet how to put a car back together, but its no real help as everybody is either talking words that you do not understand, or asking you if you have the tools that you need to get your car jigsaw puzzle working again.

After a while, it becomes obvious to you that the only solution is to get a car repair expert to come and look at the mess you have created and to help you sort it out.

Does that situation sound familiar?

What do you think you really should to do now?
