Disclosed is a device ( 30 ) for manually controlling the position of switching means which have two extreme positions A and C and an intermediate position B. Said device comprises a crank ( 5 ) and a crankpin ( 6 ). The invention is characterized by the fact that the device comprises a translationally movable sliding member ( 1 ) that has a neutral position and is provided with guideways ( 20, 21 ), within which the crankpin ( 6 ) is displaced. Said guideways allow the crankpin to be guided towards three areas of the sliding member, in which the position thereof is stable and which correspond to the three positions of the switching means, when the sliding member is moved towards the neutral position. The inventive device has the advantage of being simple while allowing a change in the state of the motor which operates the closing element, darkening element, or sun-shading element, or sun-shading element to be controlled by means of a single movement of a rod ( 14 ).
