Thanks~
what is the name of this kind of switching??
if i only have the simple switches, which can only control one terminal~ then can i do that?? :lol:
It's called 'two way switching', if you have a switch at the top of the stairs, and one at the bottom, this is how they are wired - it's a really standard technique.
