Digital Thermatic Fan Switch with 1/4" NPT Sensor & 35mm Inline Adapter Kit

Designed to manage Electric Fans or Electric Water Pumps (EWP), this comprehensive kit includes two thermal sensors and a 35mm inline adapter for a professional cooling setup. The adapter allows for easy installation directly into the engine's radiator hose.

The switch supports 1 or 2 fans (12V or 24V applications) with a 10-second delay for the second fan to manage electrical surges. Fans will operate until the temperature falls 5°C below your set target, ensuring precise thermal management.
