This Wabco pressure switch, MPN 4410140400, is a critical component within air brake systems, specifically functioning as an air valve. It is designed for use in heavy-duty vehicles and trailers to monitor air pressure and trigger actions based on pre-set thresholds. This switch operates as a normally open device with a switching pressure of 3.0±0.4 bar and a maximum operating pressure of 12.0 bar. Its compact design, measuring 25 x 37 x 25 mm, and robust construction with an M12 x 1.5 port thread ensure reliable performance in demanding environments. The electrical connection utilizes a Tab 6.3 x 0.8 IEC - 60760 CuZn37, gal . Ag connector, and it is rated for a voltage of 12/24 V within a temperature range of -40°C to +80°C. This switch offers precise air pressure monitoring, enhancing the safety and efficiency of the braking system and meeting OE specifications. Basically, this little guy monitors the air pressure in your brake system. It’s an electrical switch that activates or deactivates based on whether the air pressure hits a specific level. It doesn't do the braking itself, it just tells other parts what’s going on with the air pressure. It’s a signal sender, if you will. Some have adjustable settings, some are preset. Think of it as part of a system of checks and balances for your air brakes. It’s often linked to things like your parking brake, or a warning light on the dash. It might also be involved in applying the spring brakes if the air pressure drops too low while you're driving—a safety feature. It’s used in a lot of heavy – duty trucks and trailers, anything that relies on air brakes. It’s usually mounted near the air tanks or relay valves. It’s pretty critical, honestly. If this switch fails, you might not get a warning when your air pressure is getting low. That can lead to serious issues—you might not realize your brakes aren't fully functioning. It’s a key piece in keeping the entire system working safely and effectively. You’ll notice if it goes bad – usually a warning light staying on when it shouldn’t, or not coming on when it should. You can find a good selection of these at places like Fixparts Online, and they're relatively straightforward to replace if you’re comfortable with basic brake system work. But if you’re at all unsure, it’s best to have a pro take a look. Our promise to you: Pressure Switch (MPN 4410140400) comes with a 12-month warranty!
