OPERATING MECHANISM FOR A SWITCH

The invention relates to a device for operating a switch having an operating lever for moving the switch between the open and closed position and an operating pin arranged to a moving part of the switch, wherein the device comprises: - a primary shaft; - a secondary shaft arranged coaxially with the primary shaft, wherein the secondary shaft has a D-shaft portion arranged for locking and releasing the operating lever of the switch by rotating the secondary shaft; - a coupling arranged between the primary shaft and the secondary shaft, wherein the coupling has rotational play to allow for a relative axial rotation of the primary and secondary shafts between a first rotational position and a second rotational position; - a spring for urging the primary shaft in a first rotational direction; - a control lever extending in a radial direction from the primary shaft for contact with the operating pin of the contact such that the operating pin can move the primary shaft in a second rotational direction; - a latch having a disengage lever extending in a radial direction from the primary shaft and a roller movable into the path of the disengage lever to limit rotation of the primary shaft in the first rotational direction; and - a reset lever extending in a radial direction from the secondary shaft.
