Body Courtesy Switch for Nissan

This small plunger sensor tells your car when a door, hood, or tailgate is open. It powers the dome light, key reminder, and alarm input. If you want reliable interior lighting, clean alarm triggers, and proper central locking logic, this switch is essential. Built to OE spec with sealed housing and consistent spring force, it resists moisture and road dust for long service.

How it works

When the panel is closed, the plunger is pressed and the circuit opens. Open the door and the plunger releases, closing the ground path so the BCM turns on the courtesy lights and signals chimes. Simple two-wire design, usually screw-mounted in the pillar or latch area.

What happens when it fails ⚠️

Common signs: dome light stuck on/off, alarm false triggers, cluster “door ajar” icon, key-in chime missing, and battery drain overnight. Corrosion, worn spring, or cracked boot cause intermittent contact. Replace at first symptoms to avoid drain and security issues.

Why choose this unit

Exact fit, stable contact resistance, weatherproof boot, quick 10‑minute install. Ideal preventative maintenance during latch or seal work.
