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.

A switching device having a pole assembly, a drive unit, and a kinematic linkage arrangement is provided. The pole assembly includes interrupter units operably connected via an interlink arrangement representing a circuit breaker and a grounding switch, respectively. The drive unit operates the interrupter units. The kinematic linkage arrangement includes at least a lever member operably connected to the interlink arrangement and the drive unit, a cam member rigidly connected to the drive unit, and an elastic member adjustably connected to the cam member. The kinematic linkage arrangement transfer a predefined torque to the drive unit to maintain the circuit breaker in an open state.
