Abstract
A switching apparatus for carrying and disconnecting electric currents includes: 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 for switching on and switching off the semiconductor switch; and a control circuit for ascertaining a voltage across the first mechanical contact arrangement as an ascertained voltage and generating an actuation signal for the switching electronics system, which actuation signal switches on the semiconductor switch, depending on the ascertained voltage. During a switching process, the switching apparatus closes the two mechanical contact arrangements with a time delay in relation to one another.
