Description

Schaltgerät mit anfänglicher Hemmung der Kinschaltbewegung Die lebensdauer von Schaltern, insbesondere beim Eiaschalten von Motoren oder Kondensatoren, kann durch "Tippen" stark vermindert werden, d.h. wenn der Schalter, statt voll eingeschaltet, nur knapp bis zur Kontaktberührung gebracht wird und dann mehrmals kurz nacheinander mit geringem Weg ein- und ausgeschaltet wird. Vom Bedienungspersonal von Maschinen wird eine solche Betätigung oft angewendet, wenn von der Maschine nur kurze Bewegungen auszuf2hren sind, Sie führt zu einer starken Erwärmung der Kontakte, zu Abbrand von Kontaktmaterial oder gar zum Verschweissen der Kontakte und sollte deshalb verhindert werden. Zu diesem Zwecke oder mindestens zum Erschweren des "Tippens" sind die verschiedensten konstruktiven Lösungen bekannt.Switching device with initial inhibition of the kinetic movement. The service life of switches, especially when switching on motors or capacitors can be greatly reduced by "tapping", i.e. if the switch, instead of being fully switched on, is only just brought to the contact point and then several times in quick succession is switched on and off with a small path. By machine operators Such an actuation is often used when the machine only makes short movements are to be carried out, it leads to a strong heating of the contacts, to burn-off of contact material or even for welding the contacts and should therefore be prevented will. For this purpose, or at least to make "typing" more difficult, the most varied constructive solutions known.

Ziel dieser Erfindung ist es, eine wenig aufwendige und nur geringen Platz beanspruchende Lösung anzugehen.The aim of this invention is to provide a low-cost and low-cost Approach space-consuming solution.
