Abstract
According to the present invention, an outer lever () of a finger lever () that can be switched to different lifts for at least one gas exchange valve is made by a deep drawing method. A salient feature of the invention is that a cup-shaped base body () having an inverse U-shaped cross-section is deep drawn, and opposing running contact surfaces () for high-lift cams are created on arms () of the outer lever () by punching out a bottom () of the base body (). Through the deep drawing method of the invention, only relatively low fabrication costs are to be expected.
