Thanks for your quick response!
So it is as simple as adding intermediate switches.
When I looked at your solution it became clear.
Ta problem solved.
Yes an od question.
I want to wiring lights in a room that has 4 doors into it so I need to be able to have multiple switching with 4 switches.
Is there a simple circuit for this or will it be down to an electronic controller?
I would prefer if it could be done with just the wiring.
