Speed limiting system for a motor vehicle including a switch and a method for positioning the switch

A speed limiting device for a vehicle including a switch which is positioned for controlling said speed limiting device;

• wherein said vehicle includes a vehicle engine, a fuel dosing apparatus for said engine, a gas pedal, a gear connection between said gas pedal and said fuel dosing apparatus and a clutch arrangement connected in said gear connection;
• wherein said speed limiting device includes a servo motor which is switched off by said switch, a servo component through which said speed limiting device actuates said clutch arrangement, a push switch, a rate of rotation indicator and a lock for said switch, and wherein after starting of said engine and depressing said gas pedal to its fully accelerated position and holding said gas pedal in the fully accelerating position, said servo component may be simultaneously adjusted in the sense of throttling said vehicle engine by means of controlling said servo motor by operation of said push switch while observing said rate of rotation indicator, with said servo component having a stroke which may be cut off corresponding to a predetermined lower boundary rate of rotation of said vehicle engine with release of said lock of said switch being taken along by said servo component by means of reversing the rotational direction of said servo motor, said speed limiting device further comprising a slide upon which said switch is arranged, said slide being displaceably supported parallel to a threaded spindle driven by said servo motor and carrying said servo component, said locking means being assigned to said slide, said speed limiting device further comprising a switchover contact bank which is connected in series with said switch and is arranged on said slide such that during the positioning of said switch, said servo component acts on said slide in such a way that said switch is actuated, with a circuit of said switch being provided which is interrupted by means of said switchover contact bank with said locking means being ineffective.
