    Abstract: A switching device includes: a first fixed contact; a second fixed contact; a contact bridge; and a first movable contact and a second movable contact that are arranged at the contact bridge. The first fixed contact is in contact with the first movable contact and the second fixed contact is in contact with the second movable contact in a switched-on state of the switching device. The first fixed contact is free of contact with the first movable contact and the second fixed contact is free of contact with the second movable contact in a switched-off state of the switching device. A load current that flows through the contact bridge between the first movable contact and the second movable contact in the switched-on state has a curved path. A path of the load current flows through the contact bridge between the first movable contact and the second movable contact.

    Abstract: A switching apparatus for conducting and interrupting electrical currents includes: a first mechanical contact arrangement; a semiconductor switch which is connected in parallel to the first mechanical contact arrangement; a second mechanical contact arrangement connected in series to the first mechanical contact arrangement; an auxiliary coil electrically isolated from a circuit of a switching drive used to move contacts of the first and second mechanical contact arrangements, and which is electromagnetically coupled to a coil of the switching drive such that a voltage is generated therein when a voltage supply of the switching drive is switched off; and a switching electronics for switching the semiconductor switch on and off, and which is supplied with the voltage generated in the auxiliary coil when the voltage supply of the switching drive is switched off. The switching electronics switches the semiconductor switch on and off multiple times according to a prespecified sequence.
