The Kleinn tank‑mount pressure switch connects with a 1/4" M NPT port and cycles an air compressor on at 90 PSI and off at 120 PSI. Designed for onboard air and horn systems, it automates pressure management so you don’t have to monitor tank levels manually. Use this sealed switch to maintain consistent operating pressure with Kleinn air tanks and compressor setups that accept 1/4" NPT fittings.
