Abstract

Es wird ein elektrisches Schaltgerät vorgeschlagen, das ein Elektromagnetsystem mit einer Spule (10) enthält. Zur Veränderung des Abstandes von Abfallspannung zu Anzugsspannung des Elektromagnetsystems bzw. der Spule werden zwei Zenerdioden (13, 14) gegeneinander in Reihe zur Spule geschaltet.

Figure 00000001
An electrical switching device is proposed which contains an electromagnetic system with a coil (10). To change the distance from the dropout voltage to the starting voltage of the electromagnetic system or the coil, two Zener diodes (13, 14) are connected in series to the coil.
