This normally closed low air pressure switch monitors the air brake system pressure in heavy-duty trucks. When pressure drops below 2-6 PSI, it opens to disable cruise control, preventing unsafe operation at low brake pressure. It is a direct aftermarket replacement for the Freightliner OEM switch FSC1749-2134 and fits various Freightliner and Mack models. Replace this switch if your cruise control fails to engage or disengage correctly, or if the switch is physically damaged or leaks.
This switch is normally closed and opens at 2-6 PSI for cruise control kick-off. Verify your vehicle uses this configuration; some models employ a normally open switch for the low air indicator at 65-75 PSI (FSC1749-1907).
