The switch features a grounding knife that effectively prevents misoperations such as 'live grounding and grounding switch closing,' eliminating the need for separate grounding lines for operators.

It can be flexibly configured for single-side grounding, double-side grounding, manual mechanisms, electric mechanisms, and integrated lightning arresters. The switch includes mechanical interlocks to prevent misoperations and can be equipped with external electromagnetic locks to interlock between the main knife and grounding knife, as well as between the isolating switch and circuit breaker.
