Abstract

An electric switch comprising a frame (2), a first stationary contact (41), a roll element (6) adapted to rotate relative to the frame (2), a rotating contact (8) stationarily fixed to the roll element (6), and an arc shutter system adapted to enhance extinguishing of an electric arc between the first stationary contact (41) and the rotating contact (8) during an opening event of the electric switch. The arc shutter system comprises a first arc shutter (91) movable relative to the frame (2) between a first position and second position, and a counterpart member (92) adapted to cooperate with the first arc shutter (91) in order to enhance extinguishing of the electric arc by squeezing the electric arc between the first arc shutter (91) and the counterpart member (92).
