Electric Fan 180 Degree Thermo Switch

The Electric Fan 180 Degree Thermo Switch by DERALE is a precision temperature-control component designed for automotive cooling systems that demand reliable, automated fan engagement. This push-in style switch integrates seamlessly into electric cooling fan kits, allowing the fan to activate at a preset temperature threshold and shut off when engine coolant drops to safe operating levels. Enthusiasts and professional mechanics rely on thermo switches to optimize cooling efficiency, reduce parasitic engine load, and extend component lifespan in both street and performance applications.

The 180-degree design refers to the electrical contact configuration, providing a simple, non-variable on/off switching mechanism that engages cooling fans at a factory-calibrated temperature point. DERALE's engineering ensures consistent performance across repeated thermal cycles, with a compact form factor (2.75 x 0.7 x 4.2 inches) that fits most factory coolant passages without modification. The lightweight construction (0.08 lbs) minimizes installation burden while the push-in connection method eliminates the need for custom plumbing fittings, making replacement straightforward for end users and technicians alike.

This thermo switch is ideal for custom cooling system builds, engine swaps, and aftermarket electric fan conversions where OEM temperature sensors are incompatible or unavailable. Installation into an existing coolant circuit takes minutes, and the push-in design accommodates standard radiator or thermostat housing ports. Whether upgrading a classic vehicle with modern cooling technology or troubleshooting an existing electric fan controller, the Electric Fan 180 Degree Thermo Switch delivers the dependable temperature sensing that keeps engines running at optimal thermal conditions.
