CA 2453788

An improved electrical interrupter apparatus includes a stationary contact and a movable contact within an enclosed region, with the movable contact being operatively connected with a drive unit that employs a pull-to-close mechanism to engage the movable contact with the stationary contact. When the contacts are desired to be closed, the drive unit applies a tensile force to an elongated rod that extends between the drive unit and a crank mechanism, which converts the tensile force in the rod into a compressive force applied to the movable contact.
