Abstract

The switch has a piston rod (6) projecting from the hydraulic cylinder, for operating the switch rod for the movable switch piece via an intermediate drive coupling. The latter uses a coupling rod (8) secured to a fork head (7) screwed to the end of the piston rod (6) via a transverse bolt (22). The fork head (7) projects into the protective sleeve (11) enclosing the piston rod (6), with a peripheral guide ring (13) precisely matched to the inner dia. of the sleeve (11). This ring (13) fits around the outside of an annular projection (14) at the end of the fork head (7), which is separated from the part of the latter incorporating the internal threaded bore for the piston rod (6) via a neck section (18). The end of the piston rod (6) is secured in the threaded bore via clamp screws (23), bridging longitudinal slits (19) in the neck section (18).
