Abstract: According to the present invention, an outer lever (1) of a finger lever (2) 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 (16) having an inverse U-shaped cross-section is deep drawn, and opposing running contact surfaces (14, 15) for high-lift cams are created on arms (4, 5) of the outer lever (1) by punching out a bottom (19) of the base body (16). Through the deep drawing method of the invention, only relatively low fabrication costs are to be expected.

Abstract: The invention proposes a switchable finger lever (1) for a valve train of an internal combustion engine having a compact structure. Through the inner lever (5) of the finger lever (1) it is possible, on the one hand, to realize a support on a gas exchange valve and, on the other hand, a mounting on a head of a support element. An outer lever (2) surrounds the inner lever (5) in longitudinal direction with its arms (3a, 3b) and is pivoted away from the inner lever (5) for effecting uncoupling. The outer lever (2) is mounted for pivoting on a cross axle (14) that extends through the inner element (5) axially above the support (8) for the gas exchange valve. At the same time, coupling elements (6) displaceable in crosswise direction are arranged axially above a complementary surface (9) that serves as a support on the support element.
