Connect the electrical cable of the mirror

Hello,

I do not know which cables need to be connected to each other. Can someone perhaps help me here?
It is strange that the black cable always shows power on the [Phasenprüfer], but is not switched.

Many thanks for your feedback.

Which cables in the 2nd photo are coming out of the wall?

Yes sorry, the 3 that come from above...

Is the right cable pure yellow or yellow-green? Today, brown is used for phase, blue for neutral conductor, yellow-green for grounding. In the past, black was also used for phase, gray for neutral conductor. Thus, it would probably correspond to brown as black and blue as gray. The lamp probably does not have grounding.

You mean the black cable provides power continuously even though you operate a switch?

Yes, the yellow is pure yellow, the grounding cable, which I also have here in the photo.

You mean the black cable supplies power continuously even though you operate a switch?

Yes, exactly.
