1. An electronic input device, comprising:

  • a knob assembly defining an annular cavity and comprising a magnetically attractable armature;

    a ratchet assembly disposed within the annular cavity and comprising a ring magnet; and

    a clutch mechanism, comprising;

    a friction disc assembly, andan electromagnet configured to generate a magnetic field that shifts the friction disc assembly between a first position in which the friction disc assembly engages the ratchet assembly and a second position in which the friction disc assembly is disengaged from the ratchet assembly,wherein the ring magnet interacts with the magnetically attractable armature to generate a ratcheting feedback in response to rotation of the knob assembly when the friction disc assembly is in the first position.
