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.

[ What is claimed is:] [1.] An actuator for a high voltage switch comprising:(a) a driver frame defining a bellerank pivot axis and a rocker pivot axis parallel to the bellcrank pivot axis but spaced in a rearward direction therefrom;(b) a bellcrank mounted to the frame for pivoting movement around

[ What is claimed is:] [1.] An actuator for a high voltage switch comprising:(a) a driver frame defining a bellerank pivot axis and a rocker pivot axis parallel to the bellcrank pivot axis but spaced in a rearward direction therefrom;(b) a bellcrank mounted to the frame for pivoting movement around the bellcrank pivot axis, the bellcrank element having an opening-side attachment and a closing-side attachment, the bellcrank being pivotable between an open position and a closed position;(c) a rocker mounted to the frame for pivoting movement around said rocker pivot axis, the rocker having an opening-side attachment point, the rocker being pivotable between a full closed position and a full open position;(d) an opening-side spring connected between the opening-side attachment points of said rocker and said bellcrank, and a closing-side spring connected between the closing-side attachment points of said rocker and said bellcrank so that said opening side spring will be deformed and energy will be stored therein upon movement of the rocker from its full closed position towards its full open position while the bellcrank remains in its closed position, and so that said closing side spring will be deformed and energy will be stored therein upon movement of the rocker from its full open position towards its full closed position while the bellcrank remains in its open position;(e) an opening-side catch for restraining said bellcrank against opening pivotal movement when said bellcrank is in said closed position thereof and a closing-side catch for restraining said bellcrank against closing pivotal movement when said bellcrank is in said open position thereof;(f) catch release means for disengaging said opening-side catch when said rocker reaches an opening unlatch position close to said full-open position during opening movement thereof and disengaging said closing-side catch when said rocker reaches a closing unlatch position close to said full-close position during closing movement thereof; and(g) mounting means for connecting said frame to a body of a high-voltage switch and connecting said bellcrank to an actuating element of the switch, whereby when the rocker pivots in closing movement said closing-side spring will be deformed until the rocker reaches the closing unlatch position, whereupon the closing-side spring will drive the bellcrank in pivoting movement towards its closed position and drive the actuating element of the switch rapidly toward a closed position thereof, and when the rocker pivots in opening movement said opening-side spring will be deformed until the rocker reaches the opening unlatch position, whereupon the opening-side spring will drive the bellcrank in pivoting movement towards its open position and drive the actuating element of the switch rapidly toward a closed position thereof.
