Abstract

See full text

A keypad includes a support, a snap disk on a first side of the support transformable from a released state to a loaded state, a cover forming a seal over the first side, a pocket in the cover, a magnet and a plunger disposed in the pocket, the plunger adapted to engage and transform the snap disk to the loaded state, a magnetic field sensor on a second side of the support, the second side opposite the first side and logic circuitry adapted to obtain a value of a strength of a magnetic field from the sensor, compare the value against a predetermined threshold value that corresponds at least approximately to the strength of a magnetic field, and when the plunger has transformed the snap disk to the loaded state and the value reaches or exceeds the threshold value, output a signal indicating that a key press occurred.
