Abstract
A joystick having a movable member that includes a shaft portion and a spherical portion wherein the shaft portion has a diameter less than the spherical portion. An actuating member is secured to the shaft portion of the movable member to provide actuation of the movable member. A magnet is disposed within the spherical portion of the movable member and positioned adjacent a three axis sensor such that the magnet moves in a hemispherical pattern along the three axis sensor to operate a device.
Claims16
A joystick comprising:
- a movable member extending from a shaft portion at a first end to a spherical portion terminating at a second end wherein the diameter of the shaft portion is less than the diameter of the spherical portion;
- an actuating member secured to the shaft portion of the movable member;
- a magnet disposed within and extending from the second end of the spherical portion of the movable member;
- and
- a three axis sensor disposed underneath and adjacent the second end of the spherical portion of the movable member such that movement of the actuating member positions the magnet in a hemispherical pattern along the three axis sensor to operate a device.

A method of manufacturing a joystick steps comprising:
- injection molding plastic to form a movable member having a shaft portion at a first end that extends into and terminates in a spherical portion and wherein the shaft portion has a diameter less than a diameter of the spherical portion;
- over molding a magnet in the spherical portion during the injection molding of the movable member;
- securing an actuating member to the first end of the movable member;
- and
- placing a three axis sensor underneath and adjacent the second end of the movable member such that movement of the actuating member positions the magnet in a hemispherical pattern along the three axis sensor.
