Abstract
A keyed device comprising a substrate and a keyswitch mounted thereon. The keyswitch includes a plunger operable to be depressed and move between a first position and a second position defining a range of motion, and a magnet coupled to the plunger. When the plunger is depressed, the magnet is operable to pass through an opening of the substrate, such that when the plunger is in the first position, the magnet is configured above the opening in the substrate, and wherein the plunger is in the second position, at least a portion of the magnet is configured below the opening in the substrate. A magnetic field sensor is coupled to the substrate and configured to detect a positive and negative magnetic field generated by the magnet over the range of motion of the plunger.
