Our professional air compressor pressure switch is designed for 24-hour continuous industrial working conditions, solving four major industry problems: inaccurate pressure, disorderly start-stop, air leakage and motor burnout. Fully compatible with piston and screw air compressors.

• High Precision Pressure Control: Precisely factory-calibrated with pressure error ≤±2 PSI, stable cut-in and cut-out pressure, no pressure fluctuation, ensuring stable operation of pneumatic tools and reducing equipment failure rate.

• Silver Alloy Anti-Burn Contacts: Thickened silver alloy contacts are high-temperature resistant and arc-resistant, avoiding contact adhesion and motor burnout. More than 100,000 switching cycles, much more durable than ordinary copper contact switches.

• Leak-Proof Reinforced Diaphragm: High-toughness anti-aging rubber diaphragm resists high-pressure fatigue and cracking. Built-in high-quality unloader valve automatically releases pressure when shutdown, effectively solving pressure drop and air leakage problems, improving pressure retention performance by 80%.

• Motor Protection & Energy Saving: Optimized start-stop buffer structure avoids frequent short cycling and motor impact load, greatly extending the service life of motors, bearings and the whole machine, achieving obvious energy-saving effects.

• Universal Direct Replacement: Standard NPT interface and standard mounting hole position, 1:1 matching mainstream air compressor models. Plug-and-play installation without modification, saving installation and after-sales cost.
