PAI Parking Brake Switch
The PAI Parking Brake Switch controls air signal feedback tied to parking brake status on commercial vehicles using air-operated brake systems. The switch uses a 1/4-18 NPT thread treated with a locking compound to secure it in place under vibration exposure common around brake plumbing. It operates as a normally open switch that closes once air pressure reaches 5 psi, allowing electrical signaling tied to brake engagement status. Designed as a Navistar-universal application, the switch aligns with common air system layouts found across multiple truck platforms. As a direct service replacement, the PAI 450548 corresponds to the OE sensor part number 598860C1.
