Abstract (en)
[origin: EP2337047A1] The switch (10) has a contact pin (21) and a tulip contact (22) that are movable in an opposite direction, where the switch is filled with sulfur hexafluoride. A drive (36) e.g. hydraulic drive, is coupled with the tulip contact, and a reversing gear produces coupling between the contact pin and the tulip contact. A display element (41) is provided in a switching point display and attached to the reversing gear. The contact pin and the tulip contact are movable along a longitudinal axis. The display element is connected with a deflection shaft in a fixed manner.
