description The utility model discloses a rotary compressed-air load switch, which comprises three phases of air cylinders used for compressing insulated medium and upper static contacts and lower static contacts arranged on the air cylinders, wherein a moving contact knife is hinged on each lower static contact; a rotary piston is fixedly connected on the moving contact knife; each phase of air cylinder is an independent air cylinder; and the three phases of air cylinders assembled with the upper static contacts and the lower static contacts are assembled on a mounting frame. The rotary compressed-air load switch is simple in structure, strong in universality of spare parts, and good in on-off performance.
