Is it possible to use three two-way switches on one ceiling light?

Hi caporicardo

To have three switches you would use 2 two way, and 1 intermediate switch.
So, yes you can have three switches for one light.

In a way. You need two x two way switches and then as many intermediate switches as you want. You could fit 100 if you wanted.

Wiring next there are a number of ways but the main one is to take the two switch wires to L1 and L2 (assuming there is a com if not that's L2 and L3) and to connect the 2 two way switches like for like. The cable is broken by the intermediate switches what ever cable goes to com is not connected to the intermediate switch.

I tried to look up the markings but it seems there is no standard. I have put a link to wiring diagram but often it does not work here and can't check until sysop has passed to post.
