It uses a female oval connector, M12 female fitting thread, and a 2-terminal layout for direct pressure-switch service on the A\/C circuit.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eLow cut-out pressure switch for HVAC system protection\u003c\/li\u003e\n\u003cli\u003eOperates at 6 psi low off and 28 psi low on\u003c\/li\u003e\n\u003cli\u003eSystem-mounted design with M12 female fitting thread\u003c\/li\u003e\n\u003cli\u003eFemale oval connector with 2 terminals\u003c\/li\u003e\n\u003cli\u003ePlastic and metal construction\u003c\/li\u003e\n\u003cli\u003eGreen housing for identification\u003c\/li\u003e\n\u003cli\u003eMeets or exceeds OEM requirements\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eProduct Details\u003c\/h2\u003e\u003cp\u003eThis Four Seasons Pressure Switch line is built for HVAC service where accurate low-pressure cut-off control is required. Part number 37811 is a pressure-style switch that helps manage compressor operation based on system pressure, supporting proper A\/C cycling in vehicles that use a low cut-out switch. It is a direct-fit style replacement for applications calling for this connector and thread configuration, including select Honda Civic and other vehicle platforms that use the same switch specification. Four Seasons 37811 is also referenced by cross numbers such as UAC SW11423C and 172286 for the same application.\u003c\/p\u003e\u003ch2\u003eWhat It Is Used For\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eRestoring A\/C compressor cut-off control when the original pressure switch fails\u003c\/li\u003e\n\u003cli\u003eAddressing intermittent compressor cycling caused by pressure-switch faults\u003c\/li\u003e\n\u003cli\u003eCorrecting HVAC system shutdown triggered by a worn or inaccurate switch\u003c\/li\u003e\n\u003cli\u003eReplacing a damaged female connector or thread-matched pressure switch assembly\u003c\/li\u003e\n\u003cli\u003eSupporting proper low-pressure protection in automotive air conditioning systems\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eInstallation Notes and Tips\u003c\/h2\u003e\u003cp\u003eVerify the connector shape, terminal count, and M12 thread size before installation. Confirm the vehicle uses a low cut-out pressure switch with the same operating points of 6 psi low off and 28 psi low on. Inspect the HVAC circuit and related wiring for corrosion or damage before installing the replacement switch. For fitment verification, compare the original part number and connector style on the vehicle, including Honda Civic applications and other matched make\/model listings.\u003c\/p\u003e\u003ch2\u003eQuality Assurance\u003c\/h2\u003e\u003cp\u003eFour Seasons 37811 meets or exceeds OEM requirements for the specified application.
