Abstract
A multi-output switch includes a dipole magnet configured to move from a central position to either a first position or a second position and a Hall Effect sensor having a first sensitive area with a first output and a second sensitive area with a second output, wherein the sensor is relatively positioned such that when the magnet is in the central position, the first output and second output read off, when the magnet is in the first position the first sensitive area is activated and the first output reads on, and when the magnet is in the second position the second sensitive area is activated and the second output reads on. The switch may further include a magnet holder configured to house the magnet and define a pathway of movement for the magnet.
