Abstract
A multiple function control knob assembly that includes a knob, a three dimensional Hall effect sensor, a magnet, and a processor. The knob is configured to be movably rotated about an axis and movably positioned along the axis. The three dimensional Hall effect sensor is located proximate to the axis. The magnet is fixedly coupled to the knob so a magnet direction of the magnet relative to the sensor can be detected by the sensor. The processor is configured to receive a signal from the sensor indicative of the magnet direction, and determine an angular direction of the magnet about the axis and a linear position of the magnet along the axis based on the signal.
