Abstract

An electric switch comprising a frame (2), a first stationary contact (41), a rotating contact (8) and a plurality of arc extinguisher members. The plurality of arc extinguisher members has a guide protrusion system adapted to guide an electric arc (77) generated during an opening event of the electric switch to a tortuous path in which the electric arc (77) advances in the plurality of arc extinguisher members in a lateral direction parallel to a rotation axis of the rotating contact (8) thereby lengthening the electric arc. The guide protrusion system comprises a plurality of guide protrusions each protruding from a body part of the corresponding arc extinguisher member towards an adjacent arc extinguisher member and providing the shortest route for the electric arc (77) between the two arc extinguisher members.
