The previous poster was not talking about installing a fan, but
replacing the speed switch. Yes there is only one wire to supply
power from the house to the fan. But in many fans, there is a speed
switch that has one wire that bring electricity in and three that go
out. They go to three different windings (coils) in the fan motor
itself.

okay, in that case, it make sense. So between the supply and three
output wires to the fan motor, is the device called a rheostat or not?
And if not what is it called?


never mind. if you have one of those that connects to different windings
on the motor, I suppose that's just a switch. duh.
