Huivlei Heavy Duty 1-Port Air Compressor Pressure Switch, 90–125 PSI, 26A, Unloader Valve

Overview

Meet the Huivlei Heavy Duty pressure switch, built for smaller, electrically driven air compressors. This switch controls tank pressure between two preset values and suits single or two-stage compressors with amperage under 26A at 120V or 12A at 240V. A 1/4\" line runs to the check valve or compressor head for quick, reliable connections.

In real-world use, this switch delivers crisp tactile feedback as pressure cycles, while the line and port arrangement helps keep installations tidy on a wall or cabinet. The corrosion‑resistant body supports longevity in busy workshops, and the built-in ON/OFF lever gives you direct control without reaching for the compressor’s power switch.

Why choose this switch

• Durable and reliable design: 26A contacts stand up to demanding use while providing consistent cycling.
• Easy installation: a single-port connection on a compact manifold makes wiring and setup straightforward.
• Versatile compatibility: designed to work efficiently in the 90–125 PSI range with adjustable cut-in and cut-out.
• Quality materials: corrosion-resistant construction supports longevity even in challenging environments.
• Practical features: an ON/OFF lever and an optional unloader valve simplify operation and startup behavior.
