This normally closed low air pressure switch is used in parking brake warning light circuits on Freightliner and Mack applications, built as a replacement. It operates at 70 PSI and features a 1/8In-27 NPT thread with locking compound applied for a secure seal. Mounted on the air system's tank, it signals the dash warning when pressure falls below the safe braking threshold.
