It threads directly into an engine block, manifold, or cooling passage using a 3\/8-18 NPT fitting, giving it a secure, leak-resistant mount in the harsh marine environment. Electrical connection is made through a 1\/4 inch blade terminal, allowing a quick push-on connection to a warning buzzer, gauge, or alarm circuit without soldering.\u003c\/p\u003e\u003cp\u003eConstructed from stainless steel for corrosion resistance, the TS25101 carries an IP54 rating for protection against water spray and dust, and meets ETL and cULus specifications. It operates as a normally open, single-circuit (1-way), two-position switch that closes to complete the warning circuit once the trip temperature is reached. Its compact housing measures 3.81 x 1.38 x 1.63 inches and can be panel mounted or surface mounted depending on the installation.\u003c\/p\u003e\u003cp\u003eThis switch is designed to work as part of a marine audible warning system alongside oil pressure switches and a buzzer, monitoring engine temperature so operators are alerted before overheating causes damage. It is made in the United States and is sold individually.\u003c\/p\u003e\u003ch3\u003eSpecifications\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand:\u003c\/strong\u003e Sierra\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number:\u003c\/strong\u003e TS25101\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eProduct Type:\u003c\/strong\u003e Temperature Switch\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size:\u003c\/strong\u003e 3\/8-18 NPT\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Trip Point:\u003c\/strong\u003e 200 Degrees Fahrenheit\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Type:\u003c\/strong\u003e Normally Open\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCircuit Type:\u003c\/strong\u003e 1-way\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNumber of Positions:\u003c\/strong\u003e 2\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTerminal \/ Connector Type:\u003c\/strong\u003e 1\/4 inch blade terminal, female-to-male\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActuator Type:\u003c\/strong\u003e Blade\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMounting Type:\u003c\/strong\u003e Panel Mount, Surface Mount\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eContact Material:\u003c\/strong\u003e Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eColor:\u003c\/strong\u003e White\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInternational Protection Rating:\u003c\/strong\u003e IP54\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications:\u003c\/strong\u003e ETL, cULus\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 3.81 x 1.38 x 1.63 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight:\u003c\/strong\u003e 0.11 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUPC:\u003c\/strong\u003e 023121251014\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCountry of Origin:\u003c\/strong\u003e United States\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatible Vehicle Type:\u003c\/strong\u003e Marine Vehicles\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eFitment\u003c\/h3\u003e\u003cp\u003eThe Sierra TS25101 is a universal temperature switch that mounts via its 3\/8-18 NPT thread;
