Title made me think these would be keyboard switches in the same style as the "Unklicky" bed-leveling probes on 3d printers, where two magnets are used as a spring + as electrical contacts to complete a circuit.
I figure that making these hall effect based switches is more tedious due to the calibration needed. As for applications though, if the keypress could be made into an analog output, the keys could act similarly to shoulder buttons on game controllers or allow WASD/arrow keys to act similarly to a joystick.
