Pressure switches are the critical interface between your tank pressure and your motor — they tell the motor when to start (cut-in pressure) and when to stop (cut-out pressure). A failed or drifting pressure switch shows up as a compressor that short-cycles, runs continuously, fails to start, or trips breakers. The HON1010 is the factory-sourced Honeywell switch that Castair specifies for compressor installations requiring this switch model.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNote: Detailed electrical specifications (amp rating, pressure range, unloader configuration) for the HON1010 are not published on the Castair manufacturer website. Contact us at 866-217-0063 to confirm this switch is the correct match for your compressor model before ordering.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003eWhat a Pressure Switch Does on an Air Compressor\u003c\/h2\u003e\n\u003cp\u003eThe pressure switch monitors tank pressure through a 1\/4\" NPT port and controls the motor circuit. When tank pressure drops to the cut-in setpoint, the switch closes the circuit and the motor starts. When pressure reaches the cut-out setpoint, the switch opens the circuit and the motor stops. The differential between cut-in and cut-out is typically 30 PSI on Castair compressors — for example, 95 PSI cut-in \/ 125 PSI cut-out on low-range switches, or 145 PSI cut-in \/ 175 PSI cut-out on high-range switches.\u003c\/p\u003e\n\u003cp\u003eSwitches with unloader ports also control an unloader valve that vents the discharge line on shutdown, allowing the motor to restart against zero head pressure. Without an unloader, a single-phase motor has to restart against full tank pressure — which exceeds its starting torque on larger pumps and trips breakers or damages the motor capacitor.\u003c\/p\u003e\n\n\u003ch3\u003eHoneywell Pressure Switch Features\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHoneywell Construction:\u003c\/strong\u003e Honeywell is one of the most trusted names in industrial pressure switch manufacturing — proven in compressor, HVAC, and industrial automation applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCorrosion Resistant Cover:\u003c\/strong\u003e Protects the internal contacts and adjustment mechanism from shop environment moisture 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\u003eEasy to Adjust:\u003c\/strong\u003e Pressure setpoints are adjustable without disassembly on most Honeywell pressure switch designs\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCastair Factory Sourced:\u003c\/strong\u003e Castair specifies this switch model for their compressor line — ensures compatibility with factory electrical configurations\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch2\u003eCastair Pressure Switch Lineup — Finding the Right Switch\u003c\/h2\u003e\n\u003cp\u003eCastair's pressure switch selection covers different pressure ranges and configurations.
