Reversal control system for an electric motor. It is of the type comprising a control device including a box in which are arranged a control knob (4) tilting about a tilt point (5), a control rod (10) mounted free to pivot on a fixed bearing point, a support (21) for movable electrical contacts (22, 23) which is actuated by the control rod, the said movable contacts interacting with fixed electrical contacts (24, 25) associated with an electric circuit (26), and characterised in that a dished blade (17) is interposed between the control rod (10) and the fixed bearing point, the said blade being deformed during the tilting of the control knob (4) via the control rod (10), in such a way as to obtain, by a touch effect, information on the state of electrical conduction between the fixed and movable contacts. Application especially to motor car equipment. <IMAGE>
