It features a single-pole double-throw (SPDT) contact form with a maximum pressure setting of 100 psi and operates at up to 28 volts. The wetted components are constructed from 304 stainless steel with a Buna-N diaphragm, making it well-suited for applications where corrosion resistance and media compatibility are priorities. With a 2% repeatability rating and an adjustable setpoint, it delivers consistent switching performance. Licensed HVAC technicians, plumbers, and industrial service techs are the typical installers for this type of device.\u003c\/p\u003e\u003cp\u003eThis switch is appropriate for residential and light commercial systems where low pressure or vacuum sensing is required, such as HVAC equipment, compressors, pumps, and fluid handling systems. The 1\/8 inch NPT male thread connection allows straightforward integration into standard ported manifolds and plumbing assemblies. Its operating temperature range of 20 degrees F to 165 degrees F makes it suitable for most indoor mechanical room and equipment environments. The normally open and normally closed starting positions give installers flexibility in circuit design.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eSPDT contact form with both normally open and normally closed starting positions\u003c\/li\u003e\n\u003cli\u003e304 stainless steel wetted material with Buna-N diaphragm for corrosion resistance\u003c\/li\u003e\n\u003cli\u003eAdjustable setpoint with 2% repeatability for consistent pressure control\u003c\/li\u003e\n\u003cli\u003eMinimum deadband of 0.3 psi, maximum deadband of 1.00 psi\u003c\/li\u003e\n\u003cli\u003e1\/8 inch NPT male thread connection for standard integration\u003c\/li\u003e\n\u003cli\u003eCSA and UL Recognized certifications for code-compliant installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or new-installation pressure switch for low pressure and vacuum monitoring applications using 1\/8 inch NPT male ported connections in fluid and pneumatic systems.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eInstallation should be performed by a qualified technician familiar with low-voltage control wiring and pressure system safety procedures. Always isolate and depressurize the system before connecting or removing the switch. Electrical connections are made via terminals; follow applicable NEC requirements for low-voltage control circuits. Verify setpoint adjustment and deadband configuration against system design requirements before returning equipment to service.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Type\u003c\/strong\u003e: Low Pressure Vacuum\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: SPDT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Pressure Setting\u003c\/strong\u003e: 100 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Deadband\u003c\/strong\u003e: 0.3 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Deadband\u003c\/strong\u003e: 1.00 psi\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eVoltage\u003c\/strong\u003e: 28 volts\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAmperage Rating\u003c\/strong\u003e: 0.25A at 250Vdc; 0.5A at 125Vdc; 15A at 125\/250Vac\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrical Connection\u003c\/strong\u003e: Terminals\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Type\u003c\/strong\u003e: NPT Male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 1\/8 inch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWetted Material\u003c\/strong\u003e: 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDiaphragm Material\u003c\/strong\u003e: Buna-N\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRepeatability\u003c\/strong\u003e: 2%\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSetpoint Adjustability\u003c\/strong\u003e: Yes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSwitch Starting Position\u003c\/strong\u003e: Off (Normally Open); On (Normally Closed)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMinimum Operating Temperature\u003c\/strong\u003e: 20 degrees F (-7 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaximum Operating Temperature\u003c\/strong\u003e: 165 degrees F (74 degrees C)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeight\u003c\/strong\u003e: 2.91 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWidth\u003c\/strong\u003e: 2.38 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLength\u003c\/strong\u003e: 1.88 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.25 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEnclosure Rating\u003c\/strong\u003e: NEMA 1\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eStandards\u003c\/strong\u003e: CSA; UL Recognized\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: BARKSDALE\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: MSPS-JJ15SS\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"BARKSDALE","offers":[{"title":"Default Title","offer_id":51540341686578,"sku":"MSPS-JJ15SS","price":199.93,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/b642a5031d2c37a7563b57e92a7affe7.jpg?v=1785852726","url":"https:\/\/voomisupply.com\/products\/barksdale-msps-jj15ss-low-pressure-vacuum-switch-100-psi","provider":"Voomi Supply","version":"1.0","type":"link"}
