Description: This is a great switch for miniature compressors to control pressure and save electrical energy. It is durable and robust, easy to install and disassemble. Functions: High-performance plastic and metal construction product is strong and durable in use. Easy to install and disassemble. Mainly used to adjust the starting pressure and closing pressure of the air compressor. If the pressure is below 90 PSI, turn on the compressor. Pressure above 120 PSI, turn off the compressor. Double pressure gauges clearly show the current pressure value. Technical data: Condition: 100% brand new. Material: metal and plastic. Colour: as shown in the picture.
