Abstract
A multi-function switch includes a casing, a key top member, two magnets, two magnetic detectors and a micro-computer. The key top member is mounted on the casing to permit both liner movement and rotational movement in a plane parallel with a bottom face of the casing. The two magnets are arranged on the key top member to be apart from each other at a predetermined distance. The two magnetic detectors are arranged on the casing to face the magnets' respectively, at respective neutral positions in the liner movement and rotational movement. The micro-computer detects a ratio of respective voltages generated from the magnetic detectors and further processes the obtained ratio as a desired operational signal.
