A switching device for fast disconnection of short-circuit currents includes a switching bridge with a movable contacting element and a fixed contacting element. The switching bridge is operable in a closed state, in which the movable contacting element is in contact with the fixed contacting element, and an open state, in which the movable contacting element is spaced apart from the fixed contacting element. The switching device further includes an electromagnetic switching drive with a coil for generating a magnetic field and a magnet anchor, a guide sleeve to guide the movement of the magnet anchor in the magnetic field of the coil, a pyrotechnic propellant charge located in the cavity, and a supporting device for supporting the guide sleeve. The magnet anchor is arranged within the guide sleeve such that a cavity is formed below the magnet anchor.

A switching device includes an arc extinguishing chamber, an orifice for outflow of the gases from the arc extinguishing chamber, and a multilayer wire cloth or fabric having at least a first wire layer and a second wire layer. The first wire layer and the second wire layer have a respective cloth or fabric structure including respective warp yarns and weft yams. The first and second wire layers are disposed in a stacked configuration in the orifice such that a weaving direction of the warp yams of the first wire layer is rotated by an angle in relation to a weaving direction of the warp yarns of the second wire layer, and a weaving direction of the weft yarns of the first wire layer is rotated by an angle in relation to a weaving direction of the weft yarns of the second wire layer.

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.

A mobile application includes a motive power circuit having a power storage device and an electrical load, where the power storage device and the electrical load are selectively electrically coupled through a power bus. The application includes a power distribution unit (PDU) electrically interposed between the power storage device and the electrical load, where the PDU includes a breaker/relay positioned on one of a high side and a low side of the power storage device. The breaker/relay includes a fixed contact and a moveable contact selectively electrically coupled to the fixed contact, where the moveable contact allows power flow through the power bus when electrically coupled to the fixed contact, and prevents power flow through the power bus when not electrically coupled to the fixed contact. The breaker/relay includes an armature coupled to the moveable contact, and capable to open or close the motive power circuit.
