Abstract

A switchable finger lever for a valve train of an internal combustion engine is provided, with the finger lever having an inner lever which cooperates at a valve-side end region with a gas exchange valve of the internal combustion engine and is connected at a support-side end region turned away from the valve-side end region pivotally to a support. Outer levers (1a, 1b) connected pivotally to the inner lever are arranged on both sides of the inner lever while being urged against the inner lever in a pivoting direction through a spring and being capable of being coupled to the inner lever through a coupling element. The outer levers (1a, 1b) are configured with an identical structure and each outer lever (1a, 1b) is configured symmetrically to the longitudinal lever axis (2).
