A switching device assembly has an encapsulation housing. Movable active conductors are located inside the encapsulation housing. A drive unit with a gearbox is located outside of the encapsulation housing. The gearbox is part of a kinematic chain for moving an active conductor. The kinematic chain penetrates the encapsulation housing. In order to reverse the direction of a movement of the gearbox that can be transmitted, the gearbox is turned around a reversing axis and coupled into the kinematic chain.
