An electromagnetic actuator rotatable about an axis including a stator magnet circuit (2) with an inner pole (9) having a central core (11), a first pole shoe (12) forming the continuation of the core at one axial end of the stator circuit and extending through an angle of approximately 180 DEG , and a single coil (3) coaxially surrounding the central core (11), the core (11) and the coil (3) being off-center relatively to the axis of rotation; and an outer pole (10) having a lateral armature (132) in the form of a tubular sector outside the coil (3) and parallel to the core (11), and a second pole shoe (14) forming the continuation of the armature (132) at the axial end of the stator circuit and extending through an angle of approximately 180 DEG ; the ends of the central core (11) and of the armature (13) which are remote from the respective pole shoes being mutually in contact.
