This switch kit restores automatic pump operation by sensing system pressure and cycling the pump motor on and off as demand changes, which is the core function that keeps a fresh water system running without manual intervention.\u003c\/p\u003e\u003cp\u003eBuilt for 12V DC marine electrical systems, the switch uses a normally open contact design with a plunger-style actuator that responds to pressure changes in the pump housing. The switch body is constructed of brass for corrosion resistance in a marine environment, and it mounts directly to the pump housing using a surface mount configuration with screw terminals for the electrical connections.\u003c\/p\u003e\u003cp\u003eThis is a direct fit replacement part for Jabsco 36950 series water pumps, making it a straightforward swap when the original pressure switch fails or begins cycling erratically. Because it ships as a complete switch kit, no additional hardware sourcing is needed to complete the replacement.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Jabsco\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e 37121-0010\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Pressure Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage:\u003c\/strong\u003e 12V DC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Brass\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Normally Open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type:\u003c\/strong\u003e Plunger\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Surface Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal Type:\u003c\/strong\u003e Screw\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Pumps:\u003c\/strong\u003e 36950 Series Water Pumps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 671880032971\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.3 pounds\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cul\u003e\u003cli\u003eJabsco 36950 series water pumps\u003c\/li\u003e\u003c\/ul\u003e\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\u003cp\u003e\u003cstrong\u003eWhat pumps does the Jabsco 37121-0010 pressure switch fit?\u003c\/strong\u003e The Jabsco 37121-0010 is a replacement pressure switch for 36950 series water pumps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat voltage is the Jabsco 37121-0010 pressure switch rated for?\u003c\/strong\u003e This switch is rated for 12V DC marine electrical systems.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is the pressure switch made of?\u003c\/strong\u003e The 37121-0010 switch body is made of brass for corrosion resistance in marine environments.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow does the pressure switch mount to the pump?\u003c\/strong\u003e It uses a surface mount configuration that attaches directly to the 36950 series pump housing.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat type of electrical contact does this switch use?\u003c\/strong\u003e The Jabsco 37121-0010 uses a normally open contact design with a plunger-style actuator that responds to pressure changes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow are the electrical connections made on this switch?\u003c\/strong\u003e The 37121-0010 pressure switch uses screw terminals for wiring the electrical connections.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIs this a genuine Jabsco part?\u003c\/strong\u003e Yes, part number 37121-0010 is a genuine Jabsco replacement switch kit for 36950 series pumps.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhat is included in the switch kit?\u003c\/strong\u003e The Jabsco 37121-0010 kit includes the replacement pressure switch for installation on a 36950 series water pump.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eHow much does the pressure switch weigh?\u003c\/strong\u003e The Jabsco 37121-0010 pressure switch weighs 0.3 pounds.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eWhy would I need to replace this switch?\u003c\/strong\u003e A pressure switch is typically replaced when a 36950 series water pump fails to cycle on and off properly or stops responding to pressure changes.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eCan I install the 37121-0010 switch myself?\u003c\/strong\u003e The 37121-0010 is a direct fit replacement that mounts to the existing 36950 series pump housing using its screw terminal connections.\u003c\/p\u003e","brand":"Jabsco","offers":[{"title":"Default Title","offer_id":49028223140059,"sku":"ITT-37121-0010","price":70.94,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0839\/7586\/4539\/files\/ITT-37121-0010_lg__17782.1558115743.500.750.jpg?v=1785164580","url":"https:\/\/www.goodvibesmarina.com\/products\/jabsco-37121-0010-pressure-switch-for-36950-series-water-pumps","provider":"Good Vibes Marina","version":"1.0","type":"link"}
