<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 an interlocking part which is interlocked with a movable part in a rotary plate set in a protective cover and installing a hindering part to hinder the operation of the other movable part. CONSTITUTION:When an electromagnetic contactor 6 is turned on, a movable part 4 proceeds toward the arrow A and a rotary plate 10 starts to rotate on a main supporting shaft 15 as an axial center. In this case, a hindering part 18 enters in the proceeding route of a movable part 5 to hinder the movable part 5 from proceeding. When the contactor 6 is turned off, the original state is recovered. When an electromagnetic contactor 7 is turned on, the movable part 5 proceeds toward the arrow B and the rotary plate 10 starts to rotate on the main supporting shaft 15 as an axial center reversely. In this case, a hindering part 17 enters inside of the proceeding route of the movable part 4 to hinder the movable part 4 from proceeding. When the contactor 7 is turned off, the original state is recovered. In this way, when a contactor 6 (7) is excited, the contactors 7 (6) are inter-locked.</p> |
