标致307/308/C2 MT刹车灯开关 2插 9634667980 原厂替换

This replacement uses high-temperature resistant engineering plastic and copper alloy contacts identical to the original, with an internal spring fatigue-tested mechanism lasting over 100,000 cycles, more durable than some aftermarket parts. OEM number 9634667980, for manual transmission models of Peugeot 307, 308 and C2. Functionally, it detects brake pedal position, triggers tail light illumination, and sends a signal to the ECU to control shifting logic. Easy to install replacement; simply unplug the old unit and rotate the snap-fit to remove/install, no need to remove the entire pedal assembly, but battery disconnection is recommended to avoid short circuits.
