Abstract: The invention is directed to a method and an arrangement for controlling an internal combustion engine wherein the air flow to the engine is influenced at least in component ranges and in a selectable time reference to operations in the engine.

Abstract: In a known safety device, a relative position of an adjuster element with respect to a driver can be monitored, and a current path required for this purpose can be checked. To this end, two wipers must lift away from two wiper paths, depending on the position of the driver and adjuster element. Because of this liftoff, early wear of the wiper paths and considerable shifting of the switch point must be expected. In the safety device according to the invention, two switch lugs are provided on the adjuster element and a cam is provided on a base. This has the advantage above all of producing a safety device that is simple to manufacture and is durable. The safety device is especially suitable for power control systems for motor vehicles.
