Abstract: A switch for a medium voltage or high voltage switchgear includes: 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 pulls the moveable contact via the at least one flexible link and pushes the moveable contact via the at least one flexible link. Activation of the contact drive in a first mode moves the moveable contact.

Abstract: A rotary auxiliary switch for medium voltage switchgears, has a lever with a cam track, along which a driving element is movable. In order to cause the lever to be covered in such a way, the operator cannot touch the application, such that the lever is split into two complementarily lever components the two components creating a hinge, when they are mechanically mounted, the resulting cam track also being splitted into two cam track parts, such that a partly first cam track is located in the first lever component, and the partly second cam track is located in the second lever component.

Abstract: The disclosure relates to an actuator for low-, medium- or high-voltage switchgears with a drive to move at least one movable contact, with mechanical actuation energy transmission elements between the drive and the movable contact system, in which rotating and/or translating elements mechanically correspond to at least one position determining switch. To compensate mechanically for torsion and/or bending effects, the rotating and/or the translating element is divided mechanically into a first part and a second part, movable relative to each other, a tappet element being between the parts. A relative mechanical deviation of the first part to the second part can be dimensioned such that it can compensate for the mechanical deviation caused by torsion and/or bending and/or tolerance of transmission elements.
