A three way light switch, would like to disconnect one switch for the fan light?
How would I keep the other two switches still working for the main lights? I want one of the three switches connected to the ceiling fan light so it does not interfere with the other two switches. How would I know which negative wire to use?
If there are three switches, one is a four way, and the wiring will depend on which is removed. I will try and do a little diagram in a second. I do not think you will be able to make one switch dedicated to the fan without two more wires, a hot and a switch leg. Do all three switches now control the lights plus the fan?
There is no negative in AC voltage, only ungrounded and grounded conductors, sometimes referred to as hot and neutral. With 3 switches there are two 3-way and one 4-way switch. The two 3-way switches have 3 screws, the 4-way has four. The "hot" lands on the first 3-way and the other two wires (jockeys) head out to two of the screws on the 4-way. The other two screws on the four way have wires heading out to the last 3-way. The final screw on the last 3-way has a wire feeding the lights. the neutral never has to go down to where the switches are, though it may merely because the electrician ran it there first.
Eliminating the 4-way would not necessarily free anything up, because the wires would have to be made up to connect to the two three ways (the four wires would in essence become two wires). And sorry, I cannot put a diagram in here. I will find a site for it if this is screwy. The dots do not count, I had to use them for spaces, the dashes are wires.
.....3-way ........4-way ..... 3-way
...........O-----------O O--------O
Hot O O-----------O O--------O O To lights
If the 4-way comes out, the opposing wires will need to be connected to each other, no free wires.
