Ranco mini high-pressure pressure switch, NC, 20 – 26 bar, automatic, SPST, 1/4" SAE flare

The Ranco mini high-pressure pressure switch is a powerful component for monitoring and controlling high pressure ranges in refrigeration, heat pump, and HVAC systems . With a switching range of 20 to 26 bar, this model is ideal for protecting compressors and high-pressure lines from overpressure —reliable, compact, and durable.

Thanks to the integrated NC (Normally Closed) function, the circuit remains closed in the normal state. As soon as the set pressure is reached, the contact opens automatically to protect connected devices or systems from critical pressure peaks .

The automatic reset ensures that the switch automatically returns to its original position after the pressure drops, enabling uninterrupted and low-maintenance operation .

The standardized 1/4" SAE flare connection allows for quick, leak-free and solder-free installation , perfect for service calls, retrofitting or replacement in existing systems .
