Ranco mini low-pressure pressure switch, NO, 1.7 – 2.7 bar, automatic, SPST, 1/4" SAE flare

The Ranco mini low-pressure pressure switch is specifically designed for precise monitoring of low pressure ranges in refrigeration, heat pump, and HVAC systems . With a switching range of 1.7 to 2.7 bar, this switch is ideal for sensitive pressure control applications , such as evaporator circuits or small commercial refrigeration systems.

The integrated NO (Normally Open) function with SPST contact automatically closes the circuit as soon as the set pressure is reached. Thanks to the automatic reset, the switch automatically returns to its original position after a pressure drop – for safe, maintenance-free continuous operation .

The 1/4" SAE flare connection ensures quick, tool-free and leak-free installation , making it particularly attractive for use in service or retrofitting .
