Zusammenfassung:A switching device for conducting and disconnecting electric currents includes: a first mechanical contact assembly; a semiconductor switch, which is in parallel to the first mechanical contact assembly; a second mechanical contact assembly, which is connected in series to the first mechanical contact assembly; and a switching electronics, which switch on and off the semiconductor switch. The switching electronics are operable, during a closing process of the first mechanical contact assembly, to turn on the semiconductor switch after a first predetermined time period t−0 after initialization of the switching electronics, and to turn the semiconductor switch off again after a second predetermined time period t−1. The first predetermined time period t−0 is set by the switching electronics depending on the first mechanical contact assembly.
