Abstract

An electric switch has two fixed spaced-apart contact elements (21), and two movable contact elements (31,32) which under the influence of contact pressure springs (41) are pressed against the fixed contact elements (21) on opposite sides thereof to form parallel current paths in the closed position of the switch. Closing and opening of the switch are effected by means of a wedge-shaped member (53), displaceable between the movable contact elements (31, 32). The wedge-shaped member is on a linearly displaceable contact carrier (51). The movable contact elements (31, 32) are guided in such a way that they move at right angles to the direction of displacement of the contact carrier (51). Between each of the movable contact elements and the associated contact pressure spring, there is located a guide member (61) which is fixed in the contact carrier (51). The guide member (61) is formed so that upon closing of the electric switch, it is displaced, by the associated movable contact element, from a rest position, in which the movable contact element is not influenced from the associated contact pressure spring, to an operating position, in which the movable contact element is influenced by the contact pressure spring via the guide member (61). <IMAGE>
