Claim:
A switchable finger lever of a valve train of an internal combustion engine, comprising an outer lever and an inner lever extending between arms of the outer lever, wherein both of the levers can pivot relative to each other and one of the inner and outer levers has on one end on a bottom side thereof a contact area for a head of a support element, wherein in a region of the contact area there extends a longitudinal recess for a coupling element, which, when the levers are coupled, can be brought into engagement in some sections with a driving area on an end side of the other lever, and wherein on an upper side of the finger at least one contact area is provided for a large lift cam, the coupling element comprises a circular or hollow cylinder, which can rotate freely in the longitudinal recess produced as a bore, the driving area on the other lever is complementary to an outer shell of the coupling element at least in an engagement area on a bottom side thereof, and the longitudinal recess for the coupling element extends above the contact area for the head of the support element which is constructed as a dome or as a cylindrical depression in the outer lever, and when coupled the coupling element viewed in a longitudinal direction of the outer lever is displaced inwards under the driving area which is constructed as a circular segment in an end side of the inner lever.
