Abstract

The electrical switch is for intermediate and high voltage and is provided with switch poles, each with at least one movable contact (5) to which a movement transmission device is mechanically connected. This device is connected with a movable part of an electric motor (6) and on breaking executes a maneuvring movement to produce a breaking movement in the movable contact. The movement transmission device incorporates a gearing mechanism (3,8,10,11) with a varying gear ratio during the maneuvring movements, achieving a maximum value. The gear ratio when the maneuvring movement commences is several times less than the maximum value or nil.
