I would very much appreciate your help in selecting the most favourable solution for the implementation of the lighting control of the hallway (ground floor) - staircase - hallway (attic).
The lighting on/off would be realised as follows:
1. switching on/off only the lighting in the hallway on the ground floor (momentary switch in the hallway on the ground floor),
2. switching on/off the lighting in the entrance hall on the ground floor and in the stairwell at the same time (second momentary switch in the entrance hall on the ground floor),
3. switching on/off only the lighting in the first floor entrance hall (momentary switch in the first floor entrance hall),
4. switching on/off the lighting in the first floor entrance hall and the staircase at the same time (second momentary switch in the first floor entrance hall),
5. switching on/off the lighting in the hallway on the ground floor + in the staircase (one momentary switch in the hallway/mezzanine) and switching on/off the lighting in the hallway on the first floor + in the staircase (second momentary switch in the hallway/mezzanine).
Please give me a hint as to how such a lighting arrangement can be implemented using bistable relays.
