Abstract:
1. A contactless rotary pull switch comprising: a switch knob assembly that is rotatable about an axis to a plurality of rotational positions and that is actuatable to at least one pull position, the switch knob assembly including a knob element and a rotational shaft fixedly coupled to the knob element; a first magnet coupled to the rotational shaft so as to rotate therewith responsive to a rotation of the knob element; at least one additional magnet positioned separately from the first magnet; a first magnetic sensor configured to sense a magnetic field generated by the first magnet to identify a rotational position of the switch knob assembly; at least one additional magnetic sensor configured to sense a magnetic field generated by the at least one additional magnet to identify a pull position of the switch knob assembly; and an arm member rotatable between a number of positions to selectively enable and inhibit sensing of the magnetic field generated by the at least one additional magnet by the at least one additional magnetic sensor, so as to identify distinct pull positions of the switch knob assembly.
