Abstract
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, a coupling arranged between the primary shaft and the secondary shaft, a spring, a control lever extending in a radial direction from the primary shaft, 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.
Claims8
A device for operating a switch having an operating lever for moving the switch between an open and closed position and an operating pin arranged to a moving part of the switch, the device comprising:
- 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 primary 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;
- and
- a latch having a disengage lever extending in the radial direction from the primary shaft and a roller movable into a path of the disengage lever to limit rotation of the primary shaft in the first rotational direction.

- and
- a latch having a disengage lever extending in the radial direction from the primary shaft and a roller movable into a path of the disengage lever to limit rotation of the primary shaft in the first rotational direction,
- wherein the roller of the latch is arranged on a lever rotating around an auxiliary shaft, which is parallel to the primary shaft, wherein a spring is provided to urge the roller in the second rotational direction and in contact with the disengage lever, and
- wherein an actuator is arranged to urge the lever with the roller in the first rotational direction.
