Abstract
Device and apparatus for controlling the operating mode of a coupling assembly, coupling and control assembly and electric motor disconnect and pass through assemblies are provided. The device is a switchable linear actuator device to control the operating mode of a coupling assembly. A plurality of magnetic sources produce corresponding magnetic fields to create a net translational force. A stator structure includes at least one electromagnetic source and a translator structure includes a permanent magnet source magnetically coupled to the stator structure across a radial air gap. The translator structure is supported for translational movement relative to the stator structure along an axis between first and second stable axial end positions which correspond to first and second operating modes of the coupling assembly and an unstable axial equilibrium position between the end positions. The translator structure translates along the axis between the different positions upon experiencing the net translational force.
