Pressure switches turn a water pump or air compressor on and off automatically. When pressure drops below the cut-in setting the switch starts the motor, and when it reaches the cut-out setting it stops it.
How to choose a pressure switch
- Water pump or compressor: water pump switches such as the Square D type, Hoover FSG-2 and HPS5-A (20-40PSI), Powerhouse FSG-2 and Taifu work with pressure tanks. Compressor switches from Haitun, THB, Sunny, Vespa, Powerstar and JR Kawasaki suit air compressors.
- Pressure range: match the switch to the range your system was designed for.
- Ports and connection: compressor switches come in 1-way, 3-way and 4-way versions, such as the Powerstar CS0012 and CS0014 and JR Kawasaki JRKSP-204, and in male or female threads, such as the JRKSP-205(M) and (F).
