LOW AIR SWITCH

This is a low air pressure switch for heavy-duty trucks. It monitors air brake system pressure and closes a circuit when the pressure drops to 2-6 PSI, triggering a warning light or buzzer to alert the driver of low air. It is typically replaced when the switch fails to activate or stays on continuously, which can cause false warnings or no warning at all.
