大众桑塔纳99新秀/2000型刹车灯开关 2插 322945515

Volkswagen Santana new model brake light switch (OEM 322945515, 2-pin direct plug) uses thicker copper contacts and high-temp engineering plastic housing; contact durability about 30% higher than OEM; prevents brake light from staying on or failing due to contact burn. Switch activates brake light via mechanical push rod and also triggers ECU to disable cruise or prioritize braking. Installation is entry-level: unplug old connector, rotate 30 degrees counterclockwise to remove; align new switch into slot and secure clockwise; no tools required. After installation, test by stepping on brake to ensure lights function properly.
