185 Temperature Switch Stainless Steel

The 185 Temperature Switch Stainless Steel from SPAL Advanced Technologies is a precision engine cooling control component designed for automotive enthusiasts and professional mechanics upgrading electric fan systems. This temperature-activated switch serves as the intelligent gateway between your engine's coolant temperature and auxiliary cooling equipment, allowing you to run efficient aftermarket electric fans, water pumps, or additional cooling circuits.

Constructed from stainless steel, the 185 Temperature Switch resists corrosion and thermal cycling stress that destroys lower-grade brass or plastic housings in high-performance environments. The switch uses a sealed bimetal sensing element that expands and contracts with precise repeatability, closing an electrical circuit when coolant reaches 185 degrees and opening again as temperature drops below setpoint. This binary on/off design eliminates complex wiring logic—a direct relay trigger that pulls low amperage at activation, making integration straightforward.

The compact form factor allows installation in tight engine bay locations where space is critical, making it ideal for custom hot rods, classic car upgrades, or modern engine optimizations for track duty. With reliable activation at the critical 185-degree Fahrenheit threshold, this switch is perfect for managing multiple cooling stages or wiring a single fan. Its lightweight design ensures it won't add unnecessary bulk to your setup.
