A high-voltage assembly contains a switching device. The switching device contains a gear having two coupling rods that can be pivoted in a predetermined pivot plane and that displace an electric contact element during pivoting, whereby the switching position of the switching device can be varied. In a first switching position, the switching device connects a first connection to a second connection, and in a second switching position, it connects the first connection to a third connection, and in a third switching position, the three connections remain unconnected. A drive axis of a drive is arranged perpendicular to a pivot plane of the coupling rods, and the coupling rods are mounted such that at least one of them can pivot through the drive axis region in which the drive axis of the drive penetrates the pivot plane of both coupling rods when adjusting the switching position of the switching device.
