Abstract
A switching finger may operate in two or three states or positions and cooperate with a single motion source to achieve methods of operating an engine in corresponding two or three modes. The modes may include cylinder deactivation, main event or auxiliary modes, including lost motion braking, LIVC and EEVO. A follower for an engine valve train utilizes an adjustable support assembly that eliminates potential for partial engagement during operation. A lever engagement member or latch is disposed for movement on the follower body and interacts with a lever to provide a constant contact geometry. The latch may support the lever in one or more precise positions, or permit the lever to pivot free of the latch for complete lost motion, as in cylinder deactivation applications.
