Module for a variable-lift valve train of an internal combustion engine

The disclosure relates to a preassembled module of a variable-lift valve train for an internal combustion engine. The module includes an electric linear actuator that lies on a top side of a base plate of the module. A slide plate, movable by the electric linear actuator by means of a linear guide, also lies on the top side of the base plate. A retaining wall extends under a bottom side of the base plate and has two actuation fingers. A free end of each actuation finger includes a contact surface for moving a coupling slide of a switchable rocker arm. In a region of an outer transverse side of the slide plate, a contact wall arranged in front of the electric linear actuator extends upward. The contact wall contacts an actuation pin of the electric linear actuator to move the slide plate in a longitudinal direction.
