Abstract: A linkage device adapted to control two electric switches including a main control shaft member, an actuation system including a first actuation member for actuating a control shaft of a first electric switch, and a second actuation member for actuating a control shaft of a second electric switch. A mechanism of the linkage device is provided with a torque limiting connection for each electric switch, wherein the torque limiting connection is adapted to disengage during an opening event if a torque exerted to an actuation member exceeds a predetermined limit value. The linkage device includes a stopping member system adapted to co-operate with a linkage arm system for preventing rotation of the main control shaft member to an OFF-position when the torque limiting connection of at least one linkage arm of the linkage arm system is in a disengaged position.

Abstract: An electric switch including a frame, a first stationary contact stationarily fixed to the frame, a contact support element adapted to move relative to the frame between a first position and second position, a movable contact stationarily fixed relative to the contact support element and having a longitudinal direction, a first arc shutter, and an actuation system for moving and guiding the first arc shutter during an opening event. The actuation system includes a first actuator member stationarily fixed relative to the frame, and a second actuator member stationarily fixed relative to the first arc shutter. The first arc shutter is adapted to move in an outward direction during the opening event, wherein the outward direction is parallel to the longitudinal direction of the movable contact.
