The present invention concerns a shutoff apparatus that can be controlled In either front or side mode, consisting of a minimum number of parts and resulting in a simple, economical, mechanically dependable, and compact unit. The shutoff apparatus (1) includes a rotating control element (20) in the shape a star with four branches (22), provided with a profiled extremity (25) and connected to the control rod (5) oriented toward one of the other of the two control axes (A, B) corresponding to front and lateral control modes, respectively. The present invention has a transmission element (30) connected to movable contacts (7) and equipped with inclined ramps transforming rotational movement by the control element (20) on one or the other of the two control axes (A, B) into translational movement by the movable contacts (7) between the released and engaged positions, and conversely.
