I have a problem with the lights in my appartement. The current setup is below (and photos further down):
There are two switches: one is at the kitchen door frame, the other one is in the electricity box by the entrance door. It works well, however, it takes the electricity from the switch for kitchen's (and all other rooms') lighting and not from the circuit breaker marked "HALL LIGHTING", which is bad because when the breaker goes off, I'm in the darkness (this has already happened to me recently when a bulb broke).
The problem is that there are only 2 wires connecting the door frame box with the main. I see a solution in re-wiring SW1 so that it either connects the two wires or not. Then I would need some sort of a relay in place of SW2. Is such thing possible? Of course, I would like it to be low consumption and silent (I know some relays are pretty noisy).
Now the photos: Top: Door switch SW1 + the kitchen switch providing "wrong source". Bottom: Detail of the door switch and the Electricity box, it is large enough to fit some device there if needed.
Any help or suggestion is appreciated. Just for clarity: I'm in Czechia, 220V/50Hz AC
