NISSAN 25360-19P00 Door Switch Assembly

This genuine Nissan (OEM) door switch assembly (SW ASSY-DOOR, part number: 25360-19P00) is a premium electromechanical component that ensures the proper operation of the vehicle's convenience and security systems. The component's role is to accurately detect the open or closed status of the doors and transmit this information to the vehicle's body control module (BCM).

Technical Characteristics and Operation

The door switch directly controls the activation of interior courtesy lighting, instrument cluster warning indicators, and the factory alarm and central locking systems. The factory OEM design ensures perfect electrical contact and long-term, reliable operation during everyday use.

• Material Composition: High-strength, wear-resistant plastic housing with corrosion-resistant metal contacts.
• Connection: Factory-specification connector socket for quick, modification-free installation.
• Environmental Resistance: Excellent dust and moisture resistance, preventing contact oxidation.
• Operating Principle: Spring-loaded push-button switch (normally closed or normally open circuit).

Typical Symptoms of Failure

Door switches are exposed to continuous mechanical and environmental stresses and can wear out over time. Common symptoms of failure include:

• The interior lighting does not illuminate when the door is opened, or conversely, remains lit while driving.
• The open door indicator icon on the instrument cluster remains lit continuously, even when doors are fully closed.
• The alarm falsely triggers when locking the vehicle.
• The automatic relocking function fails to detect that a door has been opened, causing the vehicle to relock itself after opening the door.
