Abstract
An apparatus for controllably actuating a selectable coupling assembly is provided. The apparatus includes a bi-directionally movable, actuating shaft attachable to a movable element of the assembly to provide selective, small displacement element movement to linearly actuate the assembly. An excitation coil is arranged to be magnetically coupled with the shaft and to controllably move the shaft between positions which correspond to different operating modes of the assembly. A controller includes a power inlet terminal adapted to receive electrical power from a vehicle DC power source, a command input terminal adapted to receive a command signal from an electronic control unit and a power switching and supply circuit coupled to the coil to switch and supply received electrical power to the coil based on the command signal. The shaft moves the element and causes the assembly to change its operating mode when the electrical power energizes the coil.
