Switching finger follower assembly

A finger follower rocker arm assembly for variably activating a gas valve of an internal combustion engine having a camshaft having a central lobe and at least one lateral lobe adjacent a first side of the central lobe, comprising:

• a follower body having a first end for engaging the engine and a second end for engaging a valve stem of the gas valve and having a passage formed in the body between the first and second ends and having a first bore traversing the passage;
• a central follower configured for engagement with the central lobe and rotatably supported in the passage by a shaft extending through the first bore and;
• a first lateral follower configured to engage the at least one lateral cam lobe and pivotally supported on the shaft;
• and
• a latching mechanism disposed on the follower body for selectively latching the lateral follower to the body to cause the motion of the at least one lateral cam lobe to be translated to the body in a first rocker assembly mode having a first valve lift capability and for unlatching the lateral follower from the body to cause engagement of the central follower with the central camshaft lobe to provide a second rocker assembly mode having a second valve lift capability.
