Abstract: A switchable one-way clutch is able to switch between operating as a one-way clutch and a clutch that locks in both directions. The clutch includes an inner race, and an outer race that includes an inner surface with a plurality of ramped profiles. A control plate is located radially outward from the inner race and moveable in an axial direction relative to the outer race. A plurality of rollers are contactable with the outer and inner races.
