Abstract

A program control device has a cam disc and an electrical contact (1) actuated by the cam. The cam disc is rotated stepwise by an eccentrically driven rocker acting on its gear teeth. It enables reduced contact switch over time compared to known types using a simple construction. The eccentric drive (5) has a flat surface (15) in the region corresp. to the switching time for the contact. The plane of the flat surface is parallel to the plane of symmetry passing through the axis of the eccentric drive. Its edge remote from the axis activates the switching process.
