I'm no electrician but my mate reckons that you can have as many
intermediate switches as you want on a two-way circuit (think switching the
landing light on downstairs before going to bed but it's a long landing with
six rooms - he wants each room to have its own switch on the landing).
I reckon that you can have the two two-way switches as normal, with one
intermediate switch. Who's correct - and if he's right, and you can have
more than one intermediate switch, can anyone give a wiring diagram
(preferably not ASCII as I can never make head nor tail of them)?
You can have as many intermediates as you want.
Have a look he

Just keep adding intermediates between the "end stop" two-way switches.
Like the diagram :-)
http://en.wikipedia.org/wiki/Multiway_switching has a good sequence of
diagrams at the bottom showing the idea with just one intermediate which
the o/p could expand upon on paper.
