   >This big industrial switch toggled between day and night. I don’t know if it changed the operation of the system, or is just switched on some sort of a dark mode for the panel itself:

   I think we can answer that with 'yes, it changed the operation of the system. The indicator next to it is labeled in Amperes and 30 Amps is a lot of current. depending on the driving voltage at 24 V (pretty common for control panels like this one) that's 700W give or take and if it is a line voltage (220 V in poland at the time) that 6.6KW.

      You are probably right, but I feel like a gigantic dashboard like that could well use 700W in just its own lighting.

         That's true, but I would not expect it to be in a place where there was much difference between day and night lighting to begin with.
