    I'm looking for an adjustable air pressure switch to work as an auto shutoff feature for my onboard air. Something similar to the one on this cheap air compressor. Anyone familiar with a switch like this available on the market? PXL_20211127_165319143.jpg

    Remains to be seen I bought the tires and wheels the rest came along
    You need a simple 12VDC pressure switch .

    Do you plan to use a relay to energize the pressure switch ?

    If not you need a pressure switch to handle the current load.

    I'm looking for the ability to set a desired psi and have the switch turn off when it reaches that point. That way I can set it for my bike tires, truck tires on a 4-way inflator, or inflatable paddle board without having to constantly monitor the pressure gauge.

    That is what a pressure switch does you set it for your desired pressure

    you don`t need a pressure switch just a simple regulator one you can set from 1 psi to 175 psi and adjust as your demands change.

    I believe a regulator would just limit the flow of the compressor and slow the tire filling process. After looking around I think what I want is a pressure transducer ( https://www.amazon.com/dp/B074QPD5RT ) and will need to program a microcontroller with some buttons and a digital display.
