奇瑞QQ3/M1倒车灯开关 QR512-3DE372901 挂挡自动点亮

This replacement part is benchmarked against OEM standards in material and craftsmanship. The housing is made of oil- and heat-resistant engineering plastic, and the contacts are silver-plated, more wear-resistant than many low-cost aftermarket parts, with a tested lifespan able to exceed normal shifting cycles. OEM part number QR512-3DE37290, suitable for Chery QQ3 and M1 models. When shifting, it automatically lights the reverse light. Functionally, it is triggered by mechanical linkage to the circuit, with no electronic module cache risk. Replacement installation difficulty is relatively low; just unscrew the old part and tighten the threads, but avoid over-tightening to prevent cracking the housing.
