It monitors system pressure and activates a warning light or buzzer if pressure falls below a safe level, typically actuating at around 66 PSI. This normally closed, single-pole switch threads into a 1/8-27 NPT port and works with 12V or 24V electrical systems. It serves as a direct replacement for several OEM and aftermarket low-air switches, providing a critical safety alert to prevent brake failure.
