Claim 7:
8. A switchable finger follower for a valve train of an internal combustion engine, the switchable finger follower comprising:
an outer lever including a first bore, and
an inner lever including a second bore, the inner lever configure to pivot relative to the outer lever via a cylindrical shaft disposed within the first and second bores,
a gas-exchanged valve contact face arranged on an underside of a first longitudinal end of the switchable finger follower,
a pivot bearing arranged on the underside at a second longitudinal end of the switchable finger follower, the pivot bearing configured for mounting the switchable finger follower within the internal combustion engine,
a cam running face arranged on an upper side of the switchable finger follower,
at least one coupling slide configured to selectively couple the inner lever to the outer lever so as to be rotationally locked to each other, and
a cam return spring configured to brace the inner lever relative to the outer lever,
wherein the first bore includes a Gothic profile comprised of two circular arcs configured to contact the cylindrical shaft such that the outer lever is configured to pivot relative to the cylindrical shaft without radial play.
