Abstract
An actuator device for a selectable clutch having three or more clutch modes may include a dual rate piston with a stable middle position. A positive stop provides very accurate control when shifting from an end position to a middle position without overshoot. Precision position control of the actuator device facilitates consistent, stable control of the current mode of the selectable clutch.
