What is the difference between magnetic switches for open/close detection and for rotation detection?

The two types of magnetic switches detect the magnetic field in different ways. 
The open/close sensor detects the magnetic field strength, which corresponds to the distance to the magnet. 
The rotation sensor checks to see if the magnetic lines are in the same direction as its sensing direction. In doing so, it can see if the magnet is rotated or not.
