A control device (10) intended for a user (62) to choose and select functions in a vehicle, comprises a knob (12) that can be turned (R) about a main axis (P) with respect to a fixed support (60). The knob (12) comprises a neutral position (PN) in which the main axis (P) coincides with a neutral axis (N) that is fixed with respect to the support (60). The control device (10) also comprises a printed circuit board (50) on which the knob (12) and at least one direction sensor (24A) are fixed. The printed circuit board (50) is mounted with the ability to pivot with respect to the support (60) about an axis (T) transverse overall to the neutral axis (N) so as to occupy at least a first activated position (PA) in which the main axis (P) is inclined with respect to the neutral axis (N) when the knob (12) is moved in a direction orthogonal to the neutral axis (N). The direction sensor (24A) is intended to detect the activated position (PA).
