Abstract: A switching device for guiding and switching of load currents includes: a movable switching component having a first movable contact and a second movable contact; a first fixed contact and a second fixed contact; a supporting device for supporting the switching component; and a magnetic actuator. The first movable contact is in contact with the first fixed contact and the second movable contact is in contact with the second fixed contact in a switched-on state of the switching component. The first movable contact is electrically separated from the first fixed contact and the second movable contact is electrically separated from the second fixed contact in a switched-off state of the switching component. The switching component is arranged such that the switching component moves between the switched-on state and the switched-off state by at least a rotational movement of the switching component and a translational movement of the supporting device.

Abstract: The switch contacts of a MEMS relay for a circuit interrupter are coated with a thin layer of liquid metal, and the MEMS relay is disposed in a sealed enclosure containing a gas medium. The gas medium provides an environmentally desirable alternative to sulfur hexafluoride (SF6), prevents oxidation of the liquid metal coating the relay switch contacts, and has sufficient dielectric strength in order to prevent current flow after separation of the switch contacts.

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.
