The subject disclosure relates to a coil module assembly for a bi-directional clutch assembly having at least one active clutch. The coil module assembly includes a housing having an actuator housing portion and a PCB housing portion. An electromagnetic actuator is disposed in the actuator housing portion for effectuating pivotal movement of the active strut from an unlocked position to a locked position in response to an energization of the electromagnetic actuator. An integrated printed circuit board (PCB) is disposed in the PCB housing portion and is in electrical communication with the electromagnetic actuator for selectively energizing the electromagnetic actuator. The housing further includes a thermally decoupled housing portion which is disposed between the actuator housing portion and the PCB housing portion for thermally decoupling, i.e., reducing heat transfer, from the electromagnetic actuator to the PCB during selective energization of the electromagnetic actuator.

A selectable one-way clutch includes pawl members provided to a held plate rotatably via a spindle; a selector plate rotatable between a lock position where the pawl members are protrudable from the held plate and a release position where the pawl members are kept in a state the pawl members are housed in the held plate side by contacting a non-formation portion where no aperture is formed; and a device which restricts an operation of the pawl members by using volume change of material whose volume changes according to temperature change, so that the pawl members are more restricted to protrude from the first plate as an environmental temperature gets lower.
