Abstract: A multi-position automatic switching actuator for a load switch includes an oil pressure cylinder member operated by power, a latch releasing member rotating in accordance with the operation of the oil pressure cylinder member, a latch member fixedly engaged to the latch releasing member and rotating in accordance with the rotation of the latch releasing member, a latch stopping member connected to the latch member and limiting the rotation of the latch member by a predetermined angle, an elastic member disposed between the latch releasing member and the latch member for instantly rotating the latch member, and a central shaft inserted through the latch member. The actuator appropriately switches a contact position to another and carries out a multi-position switching control by employing a single actuator, thereby simplifying production, decreasing production cost, and securing safety in work operations.

Abstract: A multi-position switching actuator for a switch gear includes a control handle unit including a control protrusion and an insertion recess, a rotation member disposed at a portion spaced from a rear portion of the control handle unit and rotated by a rotation of the control handle unit, a front plate disposed between the control handle unit and the rotation member, a latch releasing member engaged to the rear surface of the rotation member, a latch driving member engaged to the latch releasing member, a location fixing member connected to the latch driving member and limiting a rotation of the latch driving member by a predetermined angle, an elastic member disposed between the latch releasing member and the latch driving member for thereby generating an instant rotation of the latch driving member, and a central shaft for being inserted from a rear portion of the latch driving member toward the front of the multi-position switching actuator.
