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.
