Zusammenfassung:The drive rod (1) of plastic material is used for the operation of high voltage switches. The rod is of cylindrical form and has formed ribs. At both ends of the rod are cross holes (5,6) that receive coupling pins (7) to secure gable end connectors (8). The holes are formed such that a constant diameter section, matching that of the bolt(7), is limited to one third of the length of the hole. On either side of the section the hole has a curved profile with a radius equal to 10-15 times the constant diameter.
