Switching apparatus for carrying and disconnecting electric currents, and switchgear having a switching apparatus of this kind

A switching apparatus for carrying and disconnecting electric currents, comprising:

• a first mechanical contact arrangement;
• a second mechanical contact arrangement which is connected in series with the first mechanical contact arrangement;
• a semiconductor switch which is connected in parallel to the first mechanical contact arrangement;
• a switching electronics system configured to switch on and switch off the semiconductor switch;
• and
• a control circuit configured to ascertain a voltage across the first mechanical contact arrangement as an ascertained voltage and to generate an actuation signal for the switching electronics system, which actuation signal switches on the semiconductor switch, depending on the ascertained voltage,
• wherein the switching apparatus is configured such that during a switching process the two mechanical contact arrangements are closed with a time delay in relation to one another,
• wherein the control circuit comprises a switch and a low-pass filter connected upstream of the switch, and
• wherein the switch is configured to generate the actuation signal for the switching electronics system.
