Think of a keyboard switch like light switches. They have a fixed point where they activate, and all they can report is whether they're in one of two states. Hall effect switches are more like light dimmer knobs. They know exactly where they currently are and can report that information back to the computer, which has a number of advantages over traditional keyboard switches.
