ABSTRACT:
A switching device for direct-current applications includes a housing having a first wall and a second wall, a plurality of receiving areas for respective mutually substantially parallel current paths disposed in the housing. Each of the current paths has a respective stationary switching contact element and a respective movable switching contact element, the movable switching element being actuatable into a closed position and into an open position so as to form a respective air break, the respective movable switching contact elements being actuatable simultaneously. The switching device includes a plurality of arc-quenching devices associated with the current paths and disposed next to each other, and at least one magnet. The at least one magnet is configured to generate a magnetic field so as to generate a deflection force on the arcs so as to deflect the respective arcs toward at least one of the respective arc-quenching devices.
