Are all 3 speed ceiling fan switches the same?
Some fans have a switch that only turns the fan on or off, while others have a switch that powers the fan at three different speeds. Each pull of the chain takes the fan up or down a notch in speed before cycling to a stopping point. Replace either type of switch following the same procedure.

What happens inside a 3 way switch?
3-way switches have three terminals, one common (usually black color) and one pair of travelers (usually brass color). With conventional wiring, the common wire from one switch connects to line, the common wire from the other switch connects to the load (lights).
What is the common wire on a 3-way switch?

At what terminal of 3 way switch we connect wire going to the load?
The common terminal is the “bridge” between the power supply and the load (typically a light fixture). With this in mind, the wire that attaches to the common terminal is either (1) a hot wire from the main board or (2) leads to the load (fixture).
What do you do with the red wire?
The exact purpose of a red wire for a light fixture can vary. Except in rare cases, it is a hot wire or a switched hot wire. Check the wire with a non-contact voltage tester with the power and switch turned on. If the tester indicates the wire is hot, turn the switch off and retest.
