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.

Abstract: An electrical switch including a frame, a first stationary contact, a second stationary contact, a roll element and a movable contact mounted to the roll element. The roll element is rotatable around a rotation axis between a first position and a second position relative to the frame. The movable contact includes a first contact portion and a second contact portion. In the first position of the roll element, the movable contact electrically conductively connects the first stationary contact to the second stationary contact, and in the second position of the roll element the first stationary contact is electrically disconnected from the second stationary contact. The first in contact portion and the second contact portion are located on opposite sides of a centre plane perpendicular to the rotation axis.
