Abstract
An actuator for a high voltage switch has a bellcrank and a rocker pivotally mounted to a frame and connected to one another by opening and closing springs. The bellcrank is linked to the movable actuating element of a high-voltage switch. During switch closing, a catch holds the bellcrank in it open position while the operator pivots the rocker towards a closed position, thereby stretching the closing spring and storing energy in it, while allowing the opening spring to go slack. When the rocker reaches a closing unlatch position, the bellcrank is released and moves rapidly toward its closed position, thus closing the switch. The opening action is similar. The bellcrank and rocker may cooperatively define channels for constraining the springs.
