  • Patent number: 11688571
    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.
