Abstract
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.
