Claim 8:
9. A switchable finger follower for a valve train of an internal combustion engine, the switchable finger follower comprising:
an outer lever including at least one first aperture,
an inner lever including at least one second aperture, the inner lever configured to pivot relative to the outer lever via a cylindrical shaft disposed within the at least one first aperture and the at least one second aperture,
a gas exchange valve contact face at a first longitudinal end of the switchable finger follower,
a pivot bearing arranged at a second longitudinal end of the switchable finger follower,
a cam running face arranged on an upper side of the switchable finger follower, and
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,
wherein at least one of the at least one first aperture or the at least one second aperture defines a Gothic profile comprised of two circular arcs configured to contact the cylindrical shaft such that the outer lever and/or the inner lever is configured to pivot relative to the cylindrical shaft without radial play.
