Abstract
A mechanism assembly is for a vacuum circuit interrupter including a vacuum housing including a stationary contact and a moveable contact, and an operating mechanism including a drive rod. The mechanism assembly cooperates with the drive rod to open and close the contacts. The mechanism assembly includes a housing having a pair of first longitudinal openings and a pair of second longitudinal openings, the first longitudinal openings defining a first plane, the second longitudinal openings defining a different second plane. A first trunnion member is pivotally and translationally mounted with respect to the first longitudinal openings. The first trunnion member is coupled to the moveable contact. A second trunnion member is pivotally and translationally mounted with respect to the second longitudinal openings. The drive rod is pivotally connected to the second trunnion member. A pair of compression springs are biased between the first and second trunnion members.
