Abstract
A bi-stable mechanism for a vacuum interrupter. The bi-stable mechanism includes an actuator; and a cam pivotable by the actuator, the cam moving a moveable contact. Wherein a bellows assembly is positioned above a vacuum bottle and coupled to a housing. The bellows assembly includes an outer cylindrical shell surrounding an opening spring, a spring plate, a contact spring, and a bellows. The bellows assembly reciprocates the moveable contact to prevent arcing between a pair of contacts and biasing the pair of contacts apart from each other.
