Abstract
A switch for medium voltage applications is provided. The switch comprises a vacuum interrupter having a fixed contact, a movable contact movable in a first direction to and away from the fixed contact between a closed position and an open position, and a drive rod arranged to the movable contact for moving the contact between the closed position and the open position. The switch further comprises a changeover switch having a first terminal body, a second terminal body, an elongated pole body, and an operating rod. The elongate pole body is hinged with a first end to the first terminal body and rotatable between a connected position in which the second end of the pole body is in direct electrical contact with the second terminal body and a disconnected position in which the second end is disconnected from the second terminal body.
