ABSTRACT:
A linear actuator powered closing mechanism for a trip-free operating mechanism of a high current, low voltage, load break switch of the type having an operating shaft and a follower affixed to the operating shaft for rotation therewith. A lever is mounted on the operating shaft for rotation therewith. A spring connects the follower and the operating lever to bias them toward each other when the spring is energized. The closing assembly includes a linear actuator having an extendible and retractable tube. A drive rod is connected to the operating shaft to rotate the operating shaft in a spring energizing direction upon longitudinal movement of the drive rod in one direction. A mechanism connecting the actuator tube and the drive rod so that movement of the actuator tube in one direction will move the drive rod in its spring energizing direction while movement of the actuator tube in the opposite direction will not result in opposite movement of the drive rod.
