Abstract
A control knob for an appliance includes an outer control ring, a stationary hub, a rotation modulating mechanism coupled to the outer control ring and engaged with an outer surface of the stationary hub, wherein the outer control ring is rotationally operable about the stationary hub at a first rate, an indicial ring positioned around the stationary hub, wherein the indicial ring engages a portion of the rotation modulating mechanism, wherein rotation of the outer control ring at the first rate causes the rotation modulating mechanism to rotate the indicial ring about the stationary hub at a second rate, the second rate being different than the first rate and an encoder shaft positioned within the stationary hub, wherein an inner gearing mechanism extends between an exterior surface of the encoder shaft and one of the outer control ring and the indicial ring.
