Control knob

A control knob comprising:

• an encoder assembly configured to convert rotary and axial input movement into electronic signals, and
• a knob assembly attached to the encoder assembly and including an outer knob element configured to be operated by a user, wherein:
• the encoder assembly comprises a shaft encoder having a shaft that is configured to be rotated around a rotation axis and to be moved axially along the rotation axis,
• the knob assembly further comprises a bush defining a cylindrical cavity inside the outer knob element, wherein the bush has an opening towards a first side of the outer knob element facing towards the encoder assembly,
• the knob assembly further comprises a driver element extending into the bush from a second side opposite the first side, and enclosing the shaft of the shaft encoder to transfer a movement of the outer knob element to the shaft encoder,
• the encoder assembly further comprises a cylindrical bearing collar, the cylindrical bearing collar defining an inner volume that is open towards a first side and towards a second side opposite the first side, wherein the shaft encoder from the first side extends into the inner volume of the cylindrical bearing collar towards the second side, and
• the driver element extends into the inner volume of the cylindrical bearing collar from the second side towards the first side, and between the shaft of the shaft encoder and the cylindrical bearing collar.
