Ranco dual pressure switch, -0.3 – 7.0 bar & 6.0 – 32.0 bar, differential pressure 0.6 / 3.5 bar fixed, manual, flare 1/4" SAE

The Ranco dual-pressure pressure switch is a reliable and robust component for monitoring low- and high-pressure zones in commercial refrigeration and air conditioning systems, as well as industrial heat pumps . A single device monitors both pressure zones and effectively protects compressors from damage caused by overpressure or underpressure .

Thanks to the fixed differential pressures of 0.6 bar (low pressure) and 3.5 bar (high pressure), the switch ensures precise and safe shutdown when the limit values are reached. The integrated manual reset prevents accidental reactivation and makes the device ideal for safety-critical applications.

Thanks to the 1/4" SAE flare connection, installation is quick, easy, and requires no soldering – ideal for new installations and maintenance work.
