A knob for an input device includes a knob housing being rotatable on an axis, a shaft extending from the knob housing along the axis, a ratchet wheel axially coupled to the shaft with a toothed perimeter, and a ratchet arm to couple to the toothed perimeter of the ratchet wheel when the ratchet arm is engaged such that a ratcheted rotation occurs when the knob is rotated, and decouple from the toothed perimeter of the ratchet wheel when the ratchet arm is disengaged. The knob can further include a resistance wheel axially coupled to the shaft with a substantially smooth perimeter, and a resistance arm to couple to the smooth perimeter of the resistance wheel when the resistance arm is engaged such that a friction is provided when the knob is rotated, and decouple from the smooth perimeter of the resistance wheel when the resistance arm is disengaged.

A knob for an input device may include a knob housing being rotatable on an axis, a shaft coupled to and extending from the knob housing along the axis, a ratchet wheel axially coupled to the shaft and including a toothed perimeter, and a resistance wheel axially coupled to the shaft and including a smooth perimeter, where the ratchet wheel and the resistance wheel are rotatable on the axis in correspondence with a rotation of the knob housing. A biasing mechanism provides a force on its first end to cause a roller to engage with the toothed perimeter of the ratchet wheel such that a ratcheted rotation occurs when the knob housing is rotated, and further provides a force on its second end to cause the second end to engage with the smooth perimeter of the resistance wheel such that a friction is provided when the knob housing is rotated.
