Abstract
A user interface for an electronic device, the interface comprising first and second parts arranged for relative displacement, said first part comprising a magnet and said second part comprising a first hall effect sensor for sensing a displacement of said magnet along a first axis and a second hall effect sensor for sensing a displacement of said magnet along a second axis, wherein said magnet moves relative to said first and second hall effect sensors in response to movement of said second part relative to said first part; a plurality of switch settings, each of said switch settings comprised of a unique combination of a magnet position along said first axis and a magnet position along said second axis; and control electronics coupled to said first and second hall effect sensors for converting the combination of a current position of said magnet along said first axis and a current position of said magnet along said second axis into a selected one of said plurality of switch settings.
