The control knob has a hub portion rotationally supported by a bearing mounted within the protuberance, and which engages the rotatable encoder shaft. The encoder is mounted such that prior to attachment of the hub portion with the encoder shaft, the encoder is allowed a degree of movement to come into alignment with the hub portion.
