An exemplary medium or high voltage switch has a first set of contact elements and a second set of contact elements. Each contact element includes an insulating carrier carrying conducting elements. In the closed current-carrying state of the switch, the conducting elements align to form one or more current paths between terminals of the switch along an axial direction. For opening the switch, the contact elements are mutually displaced by through two drives along a direction perpendicular to the axial direction. The switching arrangement is arranged in a fluid-tight housing in a gas of elevated pressure or in a liquid. The switch has a high voltage withstand capability and fast switching times.

A mechanical latching unit for a main drive unit includes a rolling mechanical switch within a housing, with a main roller, a counter roller, a carriage and a carriage trip/locking lever, with a first joint created between the main roller and the first end of the carriage, where by the load of the traction link of the main drive unit carried out to the main roller distributes a primary force component carried out to the counter roller and a secondary force component carried out in a direction to a second end of the carriage, where by the mechanical latching unit includes a force reduction mechanism having at least two force reduction stages, a carrier reset spring fastened to the housing which resets the carriage back to a neutral respectively blocking position, and a lever reset spring which resets the carriage trip/locking lever back to a neutral respectively blocking position.
