Abstract: The present invention relates a switch for a medium voltage or high voltage switchgear. The switch comprises: a first fixed contact; a second fixed contact; a moveable contact; a first gear wheel; and a second gear wheel. In an on state of the switch the moveable contact is in a position that connects the first fixed contact to the second fixed contact. In an off state of the switch the moveable contact is in a position where the first fixed contact is not connected to the second fixed contact. Rotation of the first gear wheel is configured to move the moveable contact. Rotation of the second gear wheel is configured to intermittently rotate the first gear wheel.

Abstract: The present invention relates to a switch for a medium voltage or high voltage switchgear. The switch comprises a first fixed contact, a second fixed contact, a moveable contact, at least one flexible link, and a contact drive. In an on state of the switch the moveable contact is in a position that connects the first fixed contact to the second fixed contact. In an off state of the switch the moveable contact is in a position where the first fixed contact is not connected to the second fixed contact. The at least one flexible link is connected to the moveable contact. The at least one flexible link engages with the contact drive. The contact drive is configured to pull the moveable contact via the at least one flexible link and the contact drive is configured to push the moveable contact via the at least one flexible link. Activation of the contact drive in a first mode is configured to move the moveable contact to the position such that the switch is in the on state. Activation of the contact drive in a second mode is drive is configured to move the moveable contact to the position such that the switch is in the off state.
