<p>PURPOSE:To hinder the operation of one movable part under the condition that the other movable part is in the operational state by installing a hindering part to hinder the operation of one movable part under the condition of the other movable part is in the operational state in each one of a pair of rotary plates. CONSTITUTION:Under off condition of both of a pair of electromagnetic contactors 6, 7 and when a contactor 6 is turned on, a movable part 4 proceeds in the direction of an arrow A and a rotary plate 9 rotates around a pivot 15 serving as an axial center. In this case, a hindering part 17 enters the proceeding route of a movable part 5 and hinders the movable part 5 from proceeding. When the contactor 6 is turned off, the original state is recovered. When the electromagnetic contactor 7 is turned on, from this state the movable part 5 proceeds in the direction of an arrow B and a rotary plate 10 to rotates around a pivot 16 serving as an axial center. In this case, a hindering part 18 enters the proceeding route of a movable part 4 and hinders the movable part 4 from proceeding. When the contactor is turned off, the original state is recovered. In this way, when the contactor 6 (7) is excited, the contactor 7 (6) can be inter-locked.</p> |
