Abstract
This control device for electric motor-reduction unit intended for driving rolling shutters, roller-blinds or the like, and permitting an accidental overstepping of the electrical stop point without causing any damage in, or putting out of order, the control device, comprises a cam having a notch formed in its contour, adapted to be engaged by a follower portion of a lever so as to open a switch controlling the supply of drive current to the motor-reduction unit. The notch has a rear portion inclined laterally and rearwardly which opens into an extension of the cam contour which is level with the bottom of the notch, or located at a lower level than this bottom. When the cam rotating in a given direction oversteps the normal electrical stop point the inclined portion moves the follower laterally and the lever is moved laterally along its pivot axis against the force of spring means, but held at the same level.
