Switching device for computer key boards, has sensors that are spaced apart and are formed in snap disc to provide sensor signal representing time change of spacing between sensors and snap disc with operation of snap disc

摘要

The switching device (100) has snap disc (140) with one envelope dot (U). The sensors (150,160) that are spaced apart and are formed in the snap disc provide a sensor signal representing a time change of spacing between the sensors and the snap disc with operation of the snap disc. Independent claims are included for the following: (1) method for detecting shift operation of switching device; and (2) computer program product for detecting shift operation of switching device.
