Restore reliable operation of your Porsche's courtesy lighting system with this OE Match Door Contact Switch for Interior Light. Produced to OE-style specifications, this door contact switch is designed to activate the interior light when the door is opened and switch it off when the door is closed. Manufactured from high-quality materials with durable electrical contacts and a corrosion-resistant housing, it delivers dependable performance, precise fitment, and long service life, making it ideal for Porsche maintenance, repairs, and restoration projects.

Diagram Ref No 30

The door contact switch is mounted within the door aperture and forms part of the vehicle's interior lighting circuit. Each time the door is opened or closed, the switch operates to control the courtesy light. Over time, continual use, corrosion, dirt, and moisture can cause the switch contacts to wear or stick, resulting in unreliable interior light operation. Replacing a worn or faulty switch restores correct courtesy light function while helping to maintain battery life and convenience.  

What This Product Does:
  • Activates the interior light when the door is opened.
  • Switches the interior light off when the door is closed.
  • Provides reliable electrical switching for the courtesy light circuit.
  • Helps prevent unnecessary battery drain caused by faulty switch operation.
  • Supports correct operation of the vehicle's interior lighting system.
  • Replaces worn, corroded, or faulty door contact switches.
  • Provides an OE-style fit for straightforward installation.

Symptoms Of Wear Or Failure:
  • Interior light failing to illuminate when the door is opened.
  • Interior light remaining on after the door is closed.
  • Intermittent operation of the courtesy light.
  • Sticking or seized switch plunger.
  • Corrosion on the switch body or electrical contacts.
  • Loose or damaged switch housing.
  • Electrical faults identified during inspection or restoration.

Why Replacement Matters:

  • The door contact switch is a simple but essential electrical component that ensures the interior light operates correctly whenever the door is opened or closed. A worn or faulty switch can leave the interior unlit when entering the vehicle or cause the light to remain on continuously, potentially draining the battery and reducing overall convenience.
  • Replacing a defective door contact switch restores dependable operation of the courtesy lighting system, helping to maintain battery health, improve usability, and preserve the original functionality of the vehicle. Manufactured as a direct replacement and produced to OE-style specifications, this OE Match Door Contact Switch for Interior Light provides reliable fit, performance, and durability for Porsche maintenance, repairs, and restoration projects.
