The use of a four way switch is needed when a load (such as a light) needs to be controlled from 3 locations or more. For instance when you walk down a hallway and there is a light there are probably at least two switches one at the beginning of the hallway and one at the end. These two switches will turn the light on or off from either location. These two switches will be three way switches. When the need to control a light or a load from more that two locations arises a four way switch is introduced. A light or load can be controlled an unlimited amount of locations by adding four way switches which are wired in between the two three way switches. Think of a sandwich where the three way switches are the bread and the meat and veggies are the four way switches. You can put as much meat and veggies as you want, but you always need two slices of bread on the top and bottom.
