Multi-position automatic switching actuator for load switch

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.
