Abstract
A fast operating disconnect switch minimizes the arc that occurs when the switch contacts are opened or closed by operation of a rotor assembly while the switch is electrically energized. A powerful operating spring within the operating mechanism under the control of a handle operator assembly overcenters upon the ON-OFF as well as OFF-ON movement of the handle operator. The handle operator assembly is adapted for either left-hand or right-hand mounting to a common rotor assembly.
