Patentansprüche:Patent claims: 1. Häufig oder periodisch schaltendes Kontaktgerät mit Doppelunterbrechung durch Kontaktbrücke, bei dem auf den schaltenden Kontakt über ein elastisches Zwischenglied (Schraubenfeder, Blattfeder) eine zusätzliche Masse kontaktdruckvergrößernd einwirkt, die sich vermöge ihrer kinetischen Energie vom Augenblick der Kontaktberührung an noch in ihrer ursprünglichen Bewegungsrichtung weiterbewegen kann, dadurch gekennzeichnet, daß die Eigenfrequenz des aus der Zusatzmasse und deren Aufhängefeder gebildeten mechanischen Schwingungs systems während der Berührungszeit der Kontakte von der Eigenfrequenz, die während der Abhebezeit wirksam ist, verschieden ist.1. Frequently or periodically switching contact device with double interruption by contact bridge, in which on the switching contact An additional mass increases the contact pressure via an elastic intermediate element (helical spring, leaf spring) which acts by virtue of its kinetic energy from the moment the contact point to move on in their original direction of movement can, characterized in that the natural frequency of the additional mass and its Mechanical vibration system formed during the contact time of the suspension spring Contacts of the natural frequency, which is effective during the lift-off time, is different. 2. Kontakt nach Anspruch 1, dadurch gekennzeichnet, daß die Eigenfrequenzen des aus Zusatzmassen und Aufhäingefedern gebildeten Schwingungssystems so gewählt sind, daß die Zusatzmassen während der Berührungszeit und während der Abhebezeit des Kontakttellers mindestens angenähert je eine Halbschwingung oder Vielfaches davon ausführen.2. Contact according to claim 1, characterized in that the natural frequencies of the additional masses and suspension springs formed vibration system are chosen so that the additional masses during the contact time and during the lifting time of the contact plate at least approximately one half oscillation each or perform multiples thereof. 3. Kontakt nach Anspruch 1 und 2, dadurch gekennzeichnet, daß die Verschiedenheit der Eigenfrequenzen während Berührungs- und Abhebezeit durch Verschiedenheit der wirksamen Federkonstanten (Einspannlängen) der Aufhängefedern bewirkt wird.3. Contact according to claim 1 and 2, characterized characterized in that the difference in natural frequencies during contact and lift-off time due to the difference in the effective spring constants (clamping lengths) of the suspension springs is effected. 4. Kontakt nach Anspruch 1 und 2, dadurch gekennzeichnet, daß die Verschiedenheit der Eigenfrequenz durch Verschiedenheit der Zusatzmassen während Berührungs- und Abhebezeit bewirkt wird.4. Contact according to claim 1 and 2, characterized in that the difference in the Natural frequency due to the difference in the additional masses during contact and lift-off times is effected.
