Import Back Up Light Switch — Buy in wholesale FOB from Supplier in Taiwan

This back up light switch is an electromechanical safety component that activates reverse lamps when a vehicle transmission engages reverse gear. The unit from Exp Auto Electric Parts Co., Ltd. in Taichung, Taiwan, features a glass-fiber reinforced PBT thermoplastic housing, silver-plated copper alloy contacts (CuAg0.1), and NBR rubber seals. It is engineered for IP67 ingress protection and compliance with automotive ECE regulations, making it suitable for both OEM assembly lines and aftermarket replacement channels serving passenger vehicles, commercial trucks, and buses.

The PBT housing delivers thermal stability and mechanical strength across the temperature cycles typical in transmission-mounted applications. Silver-plated copper alloy contacts ensure low electrical resistance and resistance to fretting corrosion under vibration. NBR seals maintain elasticity in oil-exposed environments, though fluorosilicone alternatives are sometimes specified for extreme temperature ranges. The switch typically operates through mechanical linkage or hydraulic pressure sensing, with actuation forces and travel distances varying by transmission design. OEM-grade units must demonstrate consistent contact resistance, dielectric strength, and seal integrity across thousands of actuation cycles.

Automotive parts distributors, independent repair chains, and vehicle fleet operators source this component for inventory replacement programs. The switch connects via standard blade or plug terminals, with pin configurations matching specific vehicle manufacturer harness designs. Buyers should verify OE cross-reference numbers, terminal orientation, and thread or bayonet mounting specifications against their application. Importing from Taiwan offers established automotive electronics manufacturing infrastructure, with Taichung serving as a concentration point for precision electromechanical component production. Confirm packaging specifications, minimum order quantities, and whether the supplier provides individual testing certificates or batch inspection reports.

Exp Auto Electric Parts Co., Ltd. is located at No.200, Renhuagong 3rd Road, Dali District, Taichung 412, Taiwan. The company is categorised as an imported-tier supplier with a harbor trust tier, indicating basic platform verification without additional third-party auditing. The response rate is recorded at 0.00 percent with zero average response hours, which suggests the supplier has not engaged with buyer enquiries through the platform's messaging system. Buyers should therefore anticipate direct communication challenges and plan alternative contact methods.

The supplier's profile does not disclose year of establishment, employee count, production capacity, revenue figures, or specific clientele. No ISO certifications, IATF 16949 automotive quality system registration, or laboratory accreditation is mentioned in the available data. The address places the company in Taichung's industrial corridor, where automotive component manufacturing has historical concentration. Buyers evaluating this supplier should request factory audit reports, quality system certificates, and sample evaluation before committing to volume orders. The lack of response history means due diligence through independent verification channels becomes essential.
