Several light switches are non-functional, all lamps are working

Hello everyone,

I live in a condominium where several light switches are not working.

Top left - kitchen
Top right - dining area
Middle - not working
Bottom left - living area
Bottom right - not working

Is it possible that simply more light switches were installed than necessary?
Maybe one of the light switches is for a lamp at the wall outlet?
I'm just surprised that the large main switch is not working.

Never worked? If there are several that are connected, check if someone has stolen something in the fuse box.

Possibly switchable sockets?

Count switches and ignition points and the "problem" is solved.

Maybe someone has also reversed it? I would have swapped the switches accordingly, but that doesn't necessarily have to be.

Without expertise, you will not get an accurate answer there. There are numerous possibilities. Personally, I cannot imagine that switches were installed blindly.
