Collection: Pressure Switches

Air compressor pressure switches are control devices that automatically start and stop the compressor based on preset pressure levels in the air tank. When the pressure drops to a cut-in point, the switch closes the electrical circuit and turns the compressor on; once the pressure reaches the cut-out point, the switch opens the circuit and shuts the compressor off. This helps maintain consistent operating pressure while preventing over-pressurization and reducing wear on the motor. Pressure switches are commonly adjustable, allowing users to set pressure ranges suited to specific tools or applications. By automating pressure regulation, they play a key role in both the safety and efficiency of compressed air systems.
