TNAIYH Air Pressure Switch, 90-120 PSI 1/4" NPT 12V/24V DC Air Compressor Pressure Controller Switch, Automotive Tank Compression On/Off Control Accessories, Universal for SUV RV Truck

Practical Function: This product can sensitively detect changes in air pressure, transmit signals through the pins on the product, and accurately determine whether the air pressure has reached the set trigger point, ensuring that the vehicle's air pressure system remains within a safe and appropriate pressure range. This ensures that the horn operates normally at the appropriate air pressure, providing reliable operation for braking, horns, and other equipment.

High Quality Material: Our air pressure switches are made from high-quality chrome-plated iron. The iron base material has excellent mechanical strength, capable of withstanding vibrations, impacts, and tightening forces during vehicle operation, ensuring structural stability. The chrome-plated layer has high hardness, reducing friction and wear during daily use, maintaining surface integrity, and ensuring functional stability.

Wide Application: Our air pressure switch has an overall height of 1.9 inch, with a thread specification of 1/4″-18 NPT MALE, and a threaded section length of approximately 0.49 inch. This product is compatible with 12V/24V vehicle electrical systems, precisely controlling air pressure, and is suitable for air horns, compressors, and air suspension systems. It is particularly suitable for train horns, marine horns, fuel tank pressure switches, and similar applications.

Easy Installation: Installing this air pressure switch is straightforward. First, ensure the vehicle is turned off and the air pressure is released. Locate the appropriate installation position, align the 1/4″-18 NPT MALE thread with the appropriate tool, and slowly screw it in until secure. Then connect the vehicle’s air pressure system harness connector to the switch pins, and verify the installation is secure to complete the process.

Complete Package: This product's package includes 1pc air pressure switch. This product is compact and lightweight, with an overall lightweight design that occupies minimal space. Whether for in-car backup or warehouse storage, it is easy to store and does not take up much space, making storage hassle-free.
