Abstract: A switching device including a frame, a roll element, a control shaft, a drive system and a roll spring. The control shaft is adapted to control rotation of the roll element such that rotating the control shaft from an ON-position to an OFF-position carries out an opening event in which the roll element transfers from a first position to a second position. The drive system includes an actuator and an actuator spring. The drive system is adapted to rotate the roll element during the opening event to an intermediate position located between the first position and the second position. The roll spring is connected between the frame and the roll element, and is adapted to rotate the roll element to the second position during the opening event.

Abstract: An electrical switch. The electrical switch includes at least one fixed contact and a movable contact contacting the fixed contact. At least one shutter element is arranged to move in synchronism with the movable contact. The shutter element is positioned in an extended position between the fixed contact and the movable contact and in a contracted position outside the patch of the movable contact allowing the movable contact to turn from the open position to the closed position.
