A contactless rotary pull switch includes a switch knob assembly rotatable about an axis to a plurality of rotational positions and actuatable to at least one pull position, with the switch knob assembly including a knob element and a rotational shaft fixedly coupled thereto. A rotational magnet is coupled to the rotational shaft so as to rotate therewith, and at least one pull magnet is positioned separately from the rotational magnet. A rotational sensor senses a magnetic field generated by the rotational magnet to identify a rotational position of the switch knob assembly and at least one pull sensor senses a magnetic field generated by the pull magnet(s) to identify a pull position of the switch knob assembly. A rotatable arm member selectively enables/inhibits sensing of the magnetic field generated by the pull magnet(s) by the at pull sensor(s), to identify distinct pull positions of the switch knob assembly.
