Standard Ignition Air Brake Pressure Switch P/N:PS-102

Keep your air-brake system's pressure signaling working with the Standard Ignition Air Brake Pressure Switch PS-102. This switch responds to the air pressure in a vehicle's air-brake circuit and opens or closes its electrical contacts as that pressure changes, sending the signal used by the dash warning indicator or buzzer circuit. It's a direct-fit replacement across a wide range of vintage Chevrolet and International trucks, including the 1959 Chevrolet 3B, 1960-1970 Chevrolet C10 Pickup, 1969-1970 Chevrolet Blazer, 1957-1958 International A100 Truck, and 1966-1972 International M1200 — see the Buyer's Guide tab for the full 94-application list.

• Function: Reacts to air-brake system pressure and switches its electrical contacts to drive the warning circuit.
• Replacement part: If a faulty original pressure switch is the cause of a warning light or buzzer that won't respond correctly, this switch replaces it.
• Direct fit: Installs on the listed Chevrolet and International applications.

Diagnose the cause of any air-pressure warning issue before replacing, since the same symptom can come from other parts of the air-brake system. Manufacturer part number PS-102 (also PS102).
