Abstract
A switchable finger follower having at least two lift modes includes a primary lever and a secondary lever mounted for pivoting movement to the primary lever, the secondary lever includes a cam contact surface, and a lost motion contact projection. A coupling device on the primary lever includes a coupling pin that moves between a locking position, in which the secondary lever is locked to the primary lever in a lift position, and an unlocked position, in which the secondary lever is pivotable relative to the primary lever. A first lost motion idler arm is pivotally connected to the primary lever and has a distal end that contacts the lost motion contact projection. A first lost motion spring is located between the primary lever and the first lost motion idler arm that maintains a preload on the secondary lever via the first lost motion idler arm in the unlocked position.
