In our bedroom we have a 2-gang 2-way architrave switch each side of the bed.ebee said:But three way switching would beggar that up.
One gang on each is wired 1-way and operates a wall light on that side of the bed.
The other gangs are wired with an intermediate switch by the door and control the ceiling light.
It is possible to get very anal and bent out of shape about the different combinations of switch positions.
It's also possible to realise that there are more important things to worry about.
