The model number suffix \"1420\" suggests this may be a higher-amperage switch (14A\/20A or a similar rating convention), which would make it appropriate for larger motor control circuits than the HON1010 or HON1012. Pressure switches are the motor's on\/off brain — they read tank pressure and control when the motor runs, and when they fail, the entire compressor system either runs non-stop or won't run at all.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNote: Castair does not publish complete electrical specs for the HON-series switches on their website. Call 866-217-0063 and provide your compressor model number to confirm the HON1420 is the correct switch before ordering.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003ePressure Switch Operation — What You Need to Know for Replacement\u003c\/h2\u003e\n\u003cp\u003eWhen replacing a pressure switch, four things need to match your compressor's requirements:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range:\u003c\/strong\u003e The cut-in and cut-out setpoints must match your compressor's intended operating pressures. Low-range switches (95\/125 PSI) go on shop compressors; high-range switches (145\/175 PSI) go on industrial units. Wrong range and your tank either underinflates or overloads the safety valve.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage:\u003c\/strong\u003e The switch must handle the full-load amperage of the motor. Undersized switch contacts burn and weld shut. The HON1420's suffix suggests a higher amperage rating suitable for larger motors.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePhase:\u003c\/strong\u003e Single-phase and three-phase switches have different contact configurations.

Without it, the motor has to start against full head pressure, which exceeds starting torque on larger pumps.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHON1420 Pressure Switch Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHoneywell Quality:\u003c\/strong\u003e Industrial pressure switch construction designed for repeated high-cycle operation in compressor control applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Resistant Cover:\u003c\/strong\u003e Protects contacts and adjustment mechanism from shop-environment humidity, oil mist, and contamination\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUL\/CSA Listed:\u003c\/strong\u003e Meets North American electrical safety standards\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCastair Specified:\u003c\/strong\u003e Factory-sourced switch for Castair compressor installations requiring this model\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhen to Replace a Pressure Switch vs. Adjusting It\u003c\/h2\u003e\n\u003cp\u003eBefore ordering a replacement switch, try these checks:\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eIf the compressor runs but won't shut off at the correct pressure, the cut-out adjustment may have drifted — try adjusting the main spring nut before replacing the switch\u003c\/li\u003e\n\u003cli\u003eIf the compressor won't start even with an empty tank, check the cut-in setting and verify the contacts are not stuck open with a continuity check at low pressure\u003c\/li\u003e\n\u003cli\u003eIf there is visible burning on the contacts, or the switch housing is cracked or melted, replacement is the correct action — adjustment won't fix damaged contacts\u003c\/li\u003e\n\u003cli\u003eIf the switch has water or oil inside the housing, replace it — moisture contamination permanently degrades contact reliability\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCastair Pressure Switch Lineup\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePSL1 \/ PSL1X \/ PSL1MIX \/ PSL4MIX\u003c\/strong\u003e — 95-125 PSI range, various configurations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePSH1 \/ PSH1X \/ PSH1MIX \/ PSH4MIX\u003c\/strong\u003e — 145-175 PSI range, various configurations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePSAD15-230\u003c\/strong\u003e — Wide-range adjustable, 15-230 PSI\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHON1010 \/ HON1012 \/ HON1420\u003c\/strong\u003e — Honeywell OEM switches for specific Castair configurations\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePSUV\u003c\/strong\u003e — Pressure switch unloader valve (replacement unloader valve for switch body)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eWhat's in the Box\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e1 x Honeywell pressure switch (HON1420)\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eTechnical Specifications\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003ePart Number:\u003c\/strong\u003e HON1420\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Honeywell (sold through Castair)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCategory:\u003c\/strong\u003e Pressure switch — motor control for air compressors\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Ratings:\u003c\/strong\u003e Call 866-217-0063 for current specifications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePressure Range:\u003c\/strong\u003e Call 866-217-0063 and provide your compressor model number\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhy Buy From Air Compressor Factory Direct?\u003c\/h3\u003e\n\u003cp\u003eWe have specialized in Castair compressors and parts since 2016.
