Abstract
A switchable cam lever that includes an inner lever and an outer lever is provided for a valve drive of an internal combustion engine. A transverse coupling serves for connecting the outer and inner lever to one another. A cam return spring is braced between the outer and inner lever. The return spring is installed upright, wherein the coupling runs directly above a support surface, and the return spring, as viewed in a lever longitudinal direction is guided in a receptacle in the inner lever. The receptacle is situated directly and entirely in front of the support surface and is formed as a bore, and the return spring bears at one end against a base or annular collar of the bore and acts at an opposite end against a crossbar which connects two arms of the outer lever at the top side.
