Air Pressure Switch Taillyg Metal 140/175 PSI 12V

Description

Product Overview

The Taillyg Air Pressure Switch is engineered for 12 V 20 A systems, providing precise automatic control of air compressors. Constructed from high‑quality metal, the unit resists rust, corrosion, high temperatures, impact, and wear, guaranteeing a long service life. It features a 1/8″ male NPT port and a 1/4″ spade connector, with activation at 140 psi and shut‑off at 175 psi, making it ideal for air horns, train horns, marine horns, fuel‑tank pressure switches, and air‑suspension applications.

Usage

Designed for versatile use, this switch fits seamlessly into air horn installations on trucks, trains, and boats, as well as into air‑suspension systems for vehicles and industrial equipment. Its drop‑in design simplifies installation, reducing downtime for mechanics and DIY enthusiasts. Whether you are maintaining a marine horn on a yacht or calibrating a compressor for a train horn, the switch delivers consistent performance in demanding environments.

FAQ

What pressure range does the switch operate in?

The switch activates the compressor at 140 psi and deactivates it at 175 psi, providing a reliable 35 psi operating window.

Can this switch be used with marine equipment?

Yes, its corrosion‑resistant metal housing makes it suitable for marine horns and other salt‑water exposed applications.

Is the installation compatible with existing wiring?

The 1/4″ spade connector fits standard 12 V 20 A wiring harnesses, allowing a quick plug‑and‑play setup without additional adapters.

What maintenance is required?

Periodically inspect the NPT port for debris and ensure the spade connector remains tight. No regular lubrication is needed due to the self‑sealing metal design.

Will this switch work with air suspension systems?

Absolutely. Its pressure thresholds are ideal for maintaining proper air‑bag pressure in vehicle suspension setups.
