Position switching device for piston-cylinder unit i.e. gas spring, has switches arranged in inner side of ring cylinder, which lies between inner diameter of pressure pipe and outer diameter of drilling

摘要

The device has a pressure pipe (1) and a retractable and extendable piston rod (2) for force supporting of components movable relative to each other. Axes of operating magnets (8) are arranged on centre axes in a drilling (10), and the magnets are moved into a locking part (7) or the piston rod during a translational movement of the piston rod relative to magnetically operated switches (9) e.g. reed switch, along the gas spring axle. The switches are arranged in an inner side of a ring cylinder, which lies between an inner diameter of the pressure pipe and an outer diameter of the drilling.
