Thermo switch
The Thermo switch supplied by Ruian Cenwanauto Electric Epuipment Co., Ltd is an OEM‑grade temperature control device designed for Volkswagen engine cooling systems. It incorporates a bimetal strip, copper contacts, a steel housing and a polyamide insulator to achieve reliable actuation of cooling fans and temperature‑warning indicators. The switch operates within precise temperature thresholds to prevent engine overheating and matches the original equipment specifications of the vehicle. The supplier lists the component as a critical part for workshops, dealers and parts wholesalers servicing Volkswagen models.
In automotive applications the bimetal element typically moves between - 40 °C and 150 °C, providing a switching voltage of about 12 V DC and a current rating near 5 A. Contact resistance is usually below 100 mΩ, and the insulation class conforms to IEC 60068‑2‑1. Physical dimensions are commonly around 30 mm × 20 mm × 10 mm, allowing easy fit within the engine bay. The polyamide insulator offers resistance to oil and vibration, matching the durability requirements of vehicle service environments.
The switch is purchased by automotive repair shops, dealership service bays and bulk parts distributors that need to maintain vehicle reliability standards. The supplier indicates that the product is ISO certified and can be supplied under FOB or CIF terms, with flexible minimum order quantities to accommodate both small‑batch and large‑scale orders. Buyers should request the exact part number and confirm compatibility with the specific Volkswagen model before placing an order. Inspection of the bimetal strip curvature and contact integrity is recommended as part of the quality assurance process.

Sourcing Thermo switch from Ruian Cenwanauto Electric Epuipment Co., Ltd - China Import Guide
Before placing an order, importers should obtain the exact part number, confirm that the switch matches the temperature thresholds required for the target Volkswagen engine, and request the supplier’s ISO certificate to validate quality management. Verifying the material composition and dimensions against the vehicle’s service specifications reduces the risk of incompatibility. It is also advisable to ask for a sample or a detailed drawing if large quantities are planned.
The supplier offers FOB and CIF terms, so buyers need to decide whether to handle freight forwarding themselves or to have the seller arrange shipping to the destination port. Lead times are not disclosed in the listing; request an estimated production and delivery schedule before finalising the contract. Common payment methods include T/T against a pro‑forma invoice or a letter of credit, both of which should be clarified in the purchase agreement.
During production, the bimetal strip curvature and contact resistance should be inspected to ensure consistent switching performance. Importers may arrange a third‑party pre‑shipment inspection covering visual checks, dimensional verification and functional testing at the specified temperature points. Required documentation typically includes a test report, the ISO certificate, and a declaration of conformity, all of which should be secured prior to shipment.
