It features a rigid stem construction and a DPDT (double-pole, double-throw) contact form, making it suitable for control circuits that require both normally open and normally closed switching in a single device. The switch covers a temperature range of 0 to 100 degrees F and carries multiple safety and compliance certifications including UL, CSA, CE, RoHS, ATEX, and IECEx. Licensed HVAC technicians, industrial instrumentation technicians, and mechanical contractors are the typical installers for this class of device.\u003c\/p\u003e\n\u003cp\u003eThis temperature switch is rated for use across a broad range of applications including boilers and burners, heating and air conditioning systems, hydraulic and lubrication systems, food processing equipment, chemical and petrochemical plants, degreasers and evaporators, marine equipment, offshore oil rigs, power plants, ground support equipment, and pulp and paper processing. The rigid stem design supports direct immersion into process fluid or pipe installations where a fixed probe orientation is required. Its watertight housing makes it appropriate for wet or wash-down environments.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eSingle-setpoint control with DPDT contact form for flexible circuit wiring\u003c\/li\u003e\n  \u003cli\u003eTemperature range of 0 to 100 degrees F\u003c\/li\u003e\n  \u003cli\u003eRigid stem construction for direct immersion or pipe-mounted installation\u003c\/li\u003e\n  \u003cli\u003eWatertight housing rated for wet and wash-down environments\u003c\/li\u003e\n  \u003cli\u003eCertified to UL, CSA, CE, RoHS, ATEX (Sira 02ATEX1391X), ATEX CSAE 21UKEX1056X, and IECEx standards\u003c\/li\u003e\n  \u003cli\u003eSuitable for boiler controls, HVAC systems, industrial process monitoring, and marine applications\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with boilers and burners, heating and air conditioning systems, hydraulic and lubrication systems, food processing equipment, chemical and petrochemical plants, degreasers and evaporators, marine equipment, offshore oil rigs, power plants, ground support equipment, and pulp and paper processing systems where a single-setpoint temperature switch with a rigid stem is required.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInstallation should be performed by a licensed instrumentation technician, mechanical contractor, or qualified HVAC technician in accordance with applicable local codes and the NEC where electrical connections are involved. De-energize all connected circuits and isolate the process fluid before removing or installing the switch. The rigid stem requires correct immersion depth into the process medium to ensure accurate setpoint actuation. Verify contact form wiring is correct for the target control circuit before restoring power.\u003c\/p\u003e\n\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eTemperature Range\u003c\/strong\u003e: 0 to 100 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMinimum Temperature\u003c\/strong\u003e: 0 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eMaximum Temperature\u003c\/strong\u003e: 100 degrees F\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eContact Form\u003c\/strong\u003e: DPDT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eStem Type\u003c\/strong\u003e: Rigid Stem\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eHousing\u003c\/strong\u003e: Watertight\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 4 pounds\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: UL, CSA, CE, RoHS Compliant, ATEX Sira 02ATEX1391X, ATEX CSAE 21UKEX1056X, IECEx\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eStandard Information\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: ASHCROFT\u003c\/li\u003e\n  \u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: T424TS040 100F\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"ASHCROFT","offers":[{"title":"Default Title","offer_id":51540210942258,"sku":"T424TS040 100F","price":851.09,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/c81a636d0af6eac17dd60a9f7f31fe6c_0ee6c4a4-cff7-4338-b186-f6b7b021d0a1.jpg?v=1785848950","url":"https:\/\/voomisupply.com\/products\/ashcroft-t424ts040-100f-temperature-switch-dpdt-rigid-stem","provider":"Voomi Supply","version":"1.0","type":"link"}
