I have three lights A, B, C and two switches 1 and 2. How do I wire

3-way switching. Would there be any problem if both switches are on?


You could use DPST switches but I'd just put B on a pair of SPDT
switches and put a and b on their own SPST switches.




Nope, that would not work as a so called 3-way switch is single pole
DOUBLE throw.

To do what the OP desires would actually take two DPDT switches.

B would be a standard 3way hook up A and B would just require the spst
terminals

though such switches are very common (as a toggle switch) as a wall
switch for a house I have never seen such a thing. Probably could get
one somewhere but your average hardware store would not have
it...possibly an industrial supply house
