How To Wire A 1 Gang 2 Way Light Switch. I know which wires control the downstairs light and can successfully wire it in. SO, I need a bit of help and maybe diagrams on how to wire them up properly.
Here are step by step instructions on how to wire up a two way lighting circuit or to change a existing one way light switch to a two way system, this is very useful on stairs etc. as you can have a switch at the bottom and the top of the stairs.

Two light switches connected to the same power source can control a single light fixture too.
