additional switch - 3 way switch circuit
#1

I'm trying to install a ceiling fan/light assembly. The circuit has two switch controlling it. I would like to add another switch into the existing circuit. where do it start?
#2
Are the existing switches 3-way, such that they control the same fixture from two places? You want to add another switch so that you can switch the fixture from three places, or you want to add another switch so that you can control the fan and light separately?
#4
Replace one of the 3-way switches with a 4-way switch. Then run a new 12/3 (or 14/3 if on a 15-amp circuit) cable from this 4-way to the location of your new switch. Reinstall the 3-way in the new location.
Do you need specific connection information?
