ABSTRACT:
An operating mechanism for a vacuum interrupter which includes a spring driven multi-linked system moving the interrupter contacts open or closed with precise, controlled movement to minimize opening rebound, closing rebound and contact opening overtravel. Such a multi-linked system provides high contact separation forces and movement to a specific contact gap while simultaneously loading a closing spring to it's fully charged and latched state. This mechanism provides and maintains full contact pressure from the instant of contact make to the instant of contact separation.
