To have multiple independent electrical light circuits in large or adjacent rooms with many distributed switches for each circuit applying latching relays (+ pushbuttons) is a viable solution.
In large or adjacent rooms one or some extra “all off” – and “on again”, of course – push buttons may be required. By itself this is is no problem.
If a person has been forgotten and left in the now dark rooms it would be comfortable if pushing any light circuit’s pushbutton would turn the (previously lit) lights on again. This might even enhance safety in some environments.
The German post
describes a scheme this extra comfort.
Sorry for having no English version; my “electric English” is too poor to avoid miss-understanding.
Even when understanding quite few of the German text the diagrams might, hopefully, be self explaining.
