Abstract
A high voltage switching device includes a current interruption assembly having at least one vacuum chamber, a fixed contact assembly having a first fixed contact and a second fixed contact positioned inside the vacuum chamber, and first and second movable-contact assemblies including a first movable contact and a second movable contact, respectively. A single mechanism actuates the first and second movable-contact assemblies between a first position and second position. In the first position, the first and second movable contacts are electrically coupled with the first and second fixed contacts, respectively. And in the second position, the first and second moveable contacts are electrically separated the same. The first movable contact and the second movable contact move, along a reference axis, one towards the other or away from the other based on the actuating mechanism.
