Abstract

A finger lever (1) that can be switched for different cam lifts is provided. The finger lever includes an outer arm (2), between whose limbs (3) an inner arm (4) is pivotally mounted. Inside the inner arm (4), starting form one end (9), a blind borehole (16) is provided with a coupling element (5), which can be longitudinally displaced therein and which, in the event of coupling, can be displaced partially under a driver surface (18) of a crossbar (15) of the outer arm (2). Height stopping parts (34) are provided on the inner arm (4) in the form of a simple, finger-like extension of the inner arm (4) at the end (9) thereof which extend out over the crossbar (15).
