Abstract
A disconnect assembly for translating torque to shafts of a driveline. A clutch is disposed in torque translating relationship between the shafts and is movable between an engaged configuration wherein torque is translated, and a disengaged configuration wherein torque is interrupted. An actuator includes a coil that generates a first magnetic field. A slider is movable between a first stable position and a second stable position, with an armature operatively attached to the slider. The armature has a magnetic polarity pattern defined by a plurality of north and south magnetic pole regions facing the coil. The pattern configured such that predetermined changes in the magnetic field generated by the coil urge the slider from one of the stable positions to the other of the stable positions so as to cause corresponding movement of the clutch assembly between the configurations to selectively translate rotational torque between the shafts of the driveline.
