Pressure switches are the primary motor control device on an air compressor — they monitor tank pressure and open or close the motor circuit at the set cut-in and cut-out pressures. When a pressure switch fails, the compressor either runs continuously (switch contacts stuck closed), refuses to start (contacts stuck open), or cycles erratically (drifting setpoints). The HON1012 is the factory-sourced Honeywell switch for Castair compressor installations that specify this model.\u003c\/p\u003e\n\u003cp\u003e\u003cem\u003eNote: Full electrical specifications (voltage, amperage, pressure range, unloader configuration) for the HON1012 are not published on the Castair manufacturer website. Call 866-217-0063 before ordering to confirm this is the correct switch for your compressor model.\u003c\/em\u003e\u003c\/p\u003e\n\n\u003ch2\u003eHow to Tell If Your Pressure Switch Has Failed\u003c\/h2\u003e\n\u003cp\u003ePressure switch failures show up in a few distinct patterns.
