Import Engine Temperature Switch — Buy in Bulk from Supplier in China

This engine temperature switch uses a foreign bimetal disc as the temperature-sensing element, designed for mounting on engine coolant tanks to monitor temperature changes. It operates on the principle of thermal deformation, where the bimetal disc triggers contact closure at preset temperature thresholds to activate cooling systems. The switch features a dual-stage mechanism: at 95°C, it closes the low-speed contact to engage the radiator fan at 1600 RPM, and at 105°C, it closes the high-speed contact to increase fan speed to 2400 RPM for enhanced cooling intensity.

The internal mechanism relies on paraffin wax expansion to drive the plunger and rubber sealing film, overcoming spring tension to open or close contacts. It is suitable for automotive applications including cars, motorcycles, trucks, and tankers, ensuring engines maintain optimal operating temperatures. The switch is engineered for reliability under standard conditions, with a working humidity range of 95% at 20°C and atmospheric pressure between 86-106 kPa, and can be installed in any position.

Commonly used in radiator fan motor control systems, this component is critical for preventing engine overheating. Buyers typically include automotive manufacturers, aftermarket parts distributors, and repair workshops sourcing OEM or replacement thermal switches. Trade terms such as MOQ, packaging, and lead times are supplier-specific and should be confirmed directly with Dongguan Yaxun Electronic Hardware Product Co. Ltd.
