Light Switch
How do I add a switch to an existing light circuit?
I want to add a ceiling fan to a room that is wired for an overhead light. I want the fan and light to be controlled by different switches. Is it possible for me to just split the hot wire at the light switch (before the switch) and add a new switch, then run a new line to the fixture? I do have access to the attic above the room so running new wires is no problem.
Yes, that is how it is done. You can use a double switch in the same location, you just need to have another switched lead to the fan location. The biggest problem is to get the wire between the 2 points.
