Abstract
Cutoff mechanism for a motor vehicle headlight, that has a bar formed by an obturation plate carried by a movable appliance configured so as to move the plate in a plane and thus obscure a light beam to a greater or lesser extent so as to change the optical operating mode, further having a mechanism for actuating the movable appliance using an electromagnet having an induction coil associated with a ferromagnetic core, wherein the electromagnet has at least one ferromagnetic core fixed with respect to its induction coil and in that the movable appliance has at least one permanent magnet configured so as to cooperate magnetically with the ferromagnetic core.
