Drying balls are placed in the drying box 5 to absorb water vapor entering the inside of the protective cover 4 to avoid affecting the switch 2 and the normal operation of the circuit. A rectangular cavity-shaped negative pressure box 6 is fixedly connected to the upper surface of the protective cover 4, and a box-shaped dust box 7 is fixedly connected to the inner top surface of the protective cover 4. A number of suction pipes are fixedly connected to the lower surface of the negative pressure box 6, and the lower ends of the suction pipes pass through the dust box 7 to its inner top surface, so that under the action of the negative pressure box 6, the flammable and explosive dust entering the protective cover 4 is absorbed into the negative pressure box 6 through the dust box 7 for storage, thereby preventing the water vapor and flammable and explosive dust in the protective cover 4 from affecting the switch 2, avoiding leakage, improving the safety of the switch 2, and extending its service life.
