Atlas Copco CW220000AV Pressure Switch

The Atlas Copco CW220000AV pressure switch is an OEM-style replacement for electric air compressors, commonly used in Kobalt Belaire systems and other Atlas Copco–brand assemblies. It features a 1/4" NPT threaded connection for field installation and a fixed 145 psi turn-on / 175 psi turn-off (ON at 145 psi, OFF at 175 psi) setup that yields a stable pressure band and minimizes motor cycling. This switching device is specified for XC602000, XC802000, and XC802100-series compressors, making it a familiar choice when a 145/175 psi control is required across compatible hardware. The CW220000AV employs a mechanical contact to energize and de-energize the compressor motor as system pressure crosses the thresholds, delivering reliable, repeatable pressure control in hobbyist shops and light-commercial environments where consistent air performance matters.
