    Abstract: A switching device includes: a first terminal contact; a first fixed contact arranged at the first terminal contact; a contact bridge; a contact bridge carrier arranged at the contact bridge and having a barrier; a first movable contact arranged at the contact bridge; a second terminal contact; a second fixed contact arranged at the second terminal contact; a second movable contact arranged at the contact bridge; and a magnetic drive assembly including a coil and an armature, the armature being coupled to the contact bridge. The first fixed contact is in contact with the first movable contact in a switched-on state of the switching device. The first fixed contact is free of contact with the first movable contact in a switched-off state of the switching device. The second fixed contact is in contact with the second movable contact in the switched-on state of the switching device.

    Abstract: A contact unit for a switching device includes: a first fixed contact; a second fixed contact; a contact bridge; a first movable contact and a second movable contact that are arranged at the contact bridge; a first arc extinguishing chamber, a second arc extinguishing chamber, and a third arc extinguishing chamber; and an arc guiding system. 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 contact unit. 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 contact unit. The first and the second arc extinguishing chamber and the arc guiding system in coordination with each other extinguish a first arc.

    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.
