Electromechanical contactor`s actuator for industrial environment, has plate supporting force resulting from deflection and repulsion forces of one of movable contacts, which is applied to movable contact when lever is in closed position

摘要

The actuator has a lever mounted on a rotational axis parallel to a rotational axis (10) of a rotary element (1) e.g. disc, and a movable bridge (20) with movable contacts (30, 31) separated from fixed contacts (40, 41). The element and the lever are co-operated between them by a peculiar shaped specific profile and a contact plate (5). The plate supports a mechanical force resulting from a force necessary to deflect another movable contact and a repulsion force exerting between the movable and fixed contacts, which is applied to the latter movable contact when the lever is in closed position.
