Abstract

A switching device that is designed for a nominal current, and that includes two terminals that are electrically connected via a first current path and a second current path that are electrically connected in series. The first current path has a mechanical switch and the second current path has a semiconductor switch. The mechanical switch is driven with a drive having a first drive unit that is energized with a control unit, and having a second drive unit connected in parallel to the second current path. The switching device is designed in such a way that the mechanical switch is transferred into an open state when a predetermined electrical current that is less than three times the nominal current is conducted by means of the second drive unit. The invention further relates to a method for operating a switching device.
