Hubbell Industrial Controls 69JF9LY Switch R-134A When troubleshooting heat pump ice-upsThe Hubbell Industrial Controls 69JF9LY Switch is a heavy duty, NEMA 1 enclosure pressure switch engineered for precise regulation of tank pressure in small electrically driven air compressors. This industrial grade component is factory calibrated for a 140 PSI cut in and 175 PSI cut out, maintaining a consistent 30 40 PSI differential to optimize motor duty cycles and prevent unnecessary wear. As a versatile universal replacement pressure switch, the
