The invention discloses a high altitude remote control relay. The high altitude remote control relay comprises a body. The body is provided with multiple isolated bodies. The bottom of the body is provided with multiple connecting fixing openings. The top face of the body is provided with a data display screen. The upper portion of the data display screen is provided with a red light and a green light. The bottom of the data display screen is provided with a first control knob and a second control knob. The isolated bodies are made of insulation rigid materials. The first control knob portion and the second control knob portion are made of sealing water-proofing materials. According to the high altitude remote control relay, due to the fact that the isolated bodies are made of the insulation rigid materials, the isolated bodies are guaranteed to be mutually uninfluenced, and a circuit is prevented from being disordered. Due to the fact that the first control knob portion and the second control knob portion are made of the sealing water-proofing materials, during high altitude working, corrosion of wind power and rain water can be effectively avoided, and the circuit safety is protected.
