Sankei KB-637 Backup Light Switch for Manual Transmission

The Sankei KB-637 is a backup light switch designed for manual transmission applications. This electrical switch is commonly used in various Asian import vehicles including Nissan, Toyota, Mazda, Renault, and Ford models.

Key Features:

• Plunger-type switch design that activates when the transmission is shifted into reverse
• Threads directly into the transmission housing for secure installation
• Activates reverse/backup lights when the transmission engages reverse gear
• Quality replacement part manufactured by Sankei (555 brand)
• Direct replacement for worn or faulty original equipment switches

This backup light switch mounts on the side of the manual transmission case. When the vehicle is shifted into reverse, the internal mechanism depresses the switch plunger, completing the electrical circuit and illuminating the backup lights. The switch helps ensure proper operation of the vehicle's reverse lighting system for enhanced safety during backing maneuvers.
