Selector knob for a motor vehicle

A selector knob for a motor vehicle, the selector knob comprising:

• a support adapted to be attached to a component of the motor vehicle;
• a lever carried by the support in a rotatable manner about an axis among a plurality of distinct angular positions;
• a transduction assembly configured to detect information about an actual angular position of the lever and to generate a control signal corresponding to the detected information;
• and
• a cam member coupled to the support in a movable manner along a radial direction with respect to said axis, the radial direction being fixed with respect to the support, the cam member further being in contact with a radially inner surface of the lever extending about said axis and defining a plurality of grooves, each of which accommodates the cam member when the lever reaches a corresponding one of said distinct angular positions,
• wherein the transduction assembly comprises a plurality of sensors, the sensors being arranged angularly distributed about said axis and facing the lever according to respective radial directions with respect to said axis, wherein each of the sensors is configured to detect the presence of a radially-facing device fixed to the lever when the lever reaches a corresponding one of said distinct angular positions, thereby detecting the actual angular position of the lever.
