Abstract: An electric switch including a frame, a first stationary contact, a roll element adapted to rotate relative to the frame, a rotating contact stationary fixed to the roll element, and an arc extinguisher plate system. The arc extinguisher plate system includes at least one first arc extinguisher plate for extinguishing an electric arc generated during an opening event between the first stationary contact and a first contact portion of the rotating contact. The at least one first arc extinguisher plate is fixed to the roll element.

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.
