I have seen wiring diagrams on the web for 2 way switching and 3 way switching. But they seem to be the same. Is there a difference?
Yes three way switchig allows you to wire two switchs to operate a light from two differnt switchs 2 way switch is on/off one place only.
Testimonial: "20 word answer with 2 spelling errors, but not all that clear because it does not say how 2 way switch differs from a single way switch."
Sorry never know when these questions are legit a three way switch lets you work A single device or more say two lights and a fan in a room or hallway and when you switch either switch at the end of the hallway it will control the light and fan or three lights and a fan. in other words you can turn it off and on at either end of say a hall way or kitchen area without having to walk across a hallway.
A two way switch is off and on and you have to go to the single switch to turn light on or off. The three way switch requires 12/3 with ground and the single single pole double throw switch will use 12/2 with ground or if the load is light enough, and is lights only you can use 14/2 with ground. Is this better? Do you understand? A picture here would be better but I can't send them Sorry.

I believe the question is referring to (at least in Australia) "2" way switching is with "2" switch mechanisms. Which seems to be exactly the same as an American "3" way switch
And a standard switch in australia to be the same as a 2 way switch in America, wheras a "3" way switch in Australia uses an intermediate mech. Which swaps the two strappers in the middle.
