Abstract
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.
