There are numerous of pressure switches for air compressors come in market. Picking the right pressure switches is pending on what the air compressing system is. A new pressure switch is usually more precise than to repair a old one, while adjustable digital pressure switches give you more convenience when use them.

 

When the compressor plugged in air compressor system, the motor starts and the air compressor begins to pressurize. When the specified system pressure is reached, a relay will control the electrical contacts apart, breaking the circuit and stopping the motor. As air is used and tank pressure drops to a specified ‘cut-in’ setting (approximately 30 PSI below the ‘cut-off’ setting) the relay contacts close and the motor starts again. The cycle continues as long is the air compressor is in use.

 

LEFOO intelligent air compressor pressure switches are instruments of pressure measurement, display and control. The switch can automatically cut in and cut off the relay output according to the pressure in the tubing. Compared with the mechanical switch, it has the characteristics of simple operation, clear display, anti-vibration, and high control accuracy.
