Abstract
A switchable finger follower having two lift modes for a valve train of an internal combustion engine. The follower includes a primary lever with a valve stem support at the first end and a support recess at the second end. A secondary lever is pivotably mounted to the primary lever at the first end, including a coupling surface. A coupling device is located on the primary lever having a coupling pin moveable between a first locking position, in which the secondary lever is locked to the inner lever, and an unlocked position, in which the secondary lever is pivotable relative to the primary lever. The coupling pin includes a ramp surface that engages the coupling surface, and a locking arrangement locks the coupling pin in the first locking position.
