A switchable finger lever ( 1 ) for a valve drive of an internal combustion engine is provided. The inner lever ( 3 ) of the finger lever includes a piston ( 6 ) on one end thereof, that can be longitudinally displaced, and acts as a coupling element. The coupling element can be partially brought into contact with a driving surface ( 7 ) of an outer lever ( 2 ), and is provided, for example, with a rising radial profile ( 13 ) in the coupling region thereof, and from the front ( 12 ) in the coupling direction. The driving surface ( 7 ) of the outer lever ( 2 ) also has a conical contour which follows the profile ( 13 ). During coupling, a contact point (K) of the piston ( 6 ) is located on the driving surface ( 7 ) in a region of half a depth thereof. In this way, the formation of undesired edge supports is prevented during coupling. |
