How can you tell which one is the switch on the bedroom, living room, and toilet on the top of the m

I really can't see this.

You can only try them one by one, and after you try them, just mark them below.

General. The first one on the left is always empty, which means that after this is turned off, everything is out of power. So close this master switch first, and then test the others one by one.

The two with protection on the right, it is estimated that one is a toilet, one is a kitchen, and the others are the living room, bedroom, lights, etc., you can try it.

The first 2p should be total, the second and third with leakage protection are generally used to connect to the socket, and the next three can only be tried one by one.

Turn on all the lights, and then try them one by one, mark them separately with a pen, 12 is the main switch and is the socket switch.

You try to turn off a set of switches first, see that the one is out of power, and then indicate below the switch, and so on, the first one does not need to try, it is the main switch, the second is the leakage switch, and the third is also the leakage switch, but you try which one is which one.

Turn on the lights, and then try the switches one by one, and mark them on the paper under the switch with a pen after finding them.

This has to get the circuit decoration diagram to know which corresponds to which, if not, try one by one, and then paste it with a note note.

Isn't there already a label paper underneath? You can just try to make a record on the label paper. You can't see it from this diagram.
