What is the function of an air pressure switch in an air suspension system?

An air pressure switch monitors the air pressure within your suspension system. It signals the air compressor to turn on when pressure drops below a set point (like 140 PSI) and to turn off when it reaches the upper limit (like 175 PSI), helping to maintain your desired ride height and support.

What does 'sealed' mean for this pressure switch?

A sealed pressure switch has a housing designed to prevent dust, dirt, and moisture from entering the internal components. This helps to improve its longevity and reliability, especially in harsh operating conditions.

What size thread does this switch use?

This Firestone pressure switch uses a 1/8 NPMT thread. This is a common size for air fittings in many air suspension and air compressor systems, making installation generally straightforward.
