Abstract: A medium voltage load break switch includes a main contact and a knife. The knife is rotatable about a pivot point to connect to and be in contact with the main contact and to rotate about the pivot point to disconnect from and be spaced from the main contact. The load break switch also comprises a vacuum interrupter that has a fixed contact and a moveable contact. A lever rotates about a rotation point and a shaft of the moveable contact is aligned along an axis of the vacuum interrupter, and the shaft of the moveable contact is linked to the lever.

Abstract: A magnetic force compensator for at least partially compensating a closing force required to shift a valve of a pneumatic positioner into a closed position using a magnetic device, the magnetic device including a permanent magnet; and a magnetic counterpart; wherein the magnetic device and the magnetic counterpart are configured to interact to create an attracting force for the at least partially compensation of the closing force; and wherein the magnetic force compensator is configured to be mechanically coupled to the valve of the pneumatic positioner.
