Abstract
A drive mechanism is for a vacuum switching apparatus. The vacuum switching apparatus has a stationary contact and a movable contact structured to move into and out of engagement with the stationary contact in order to connect and disconnect power, respectively. The drive mechanism includes a drive rod structured to drive the movable contact into and out of engagement with the stationary contact, the drive rod being movable along a longitudinal axis, and a number of toggle assemblies each having a component and a biasing element coupled to the component. The component is coupled to the drive rod. The biasing element is structured to bias the drive rod in a direction not coinciding with the longitudinal axis.
