• The switch may be in one of three positions: "closed", "open", or "earthed", representing a natural interlocking system that prevents incorrect operation. Moving-contact rotation is driven by a fast-acting mechanism that is independent of the action of the operator.
• The device combines the breaking and disconnection functions.
• The earthing switch placed in the SF6 has a short-circuit making capacity, in compliance with standards.
• Any accidental over-pressures are eliminated by the opening of the safety membrane, in which case the gas is directed toward the back of the unit, away from the operator.
