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.

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.

Manufactured as an original-style replacement, it is ideal for repairing faulty interior lighting or replacing worn electrical components during classic Porsche restoration.
What Does the Door Contact Switch Do?
The switch is fitted within the door aperture and operates the interior courtesy light circuit.
Opening the door releases the switch, allowing the interior light to illuminate. Closing the door operates the switch and turns the light off.
Why Does It Fail?
Over time, repeated operation, moisture and corrosion can cause the electrical contacts or switch mechanism to deteriorate.
Common problems include worn contacts, sticking plungers, damaged connections and general age-related wear.
When Should It Be Replaced?
Replacement is recommended if:
- The interior light fails to illuminate when the door opens.
- The courtesy light remains on after closing the door.
- The light operates intermittently.
- The switch plunger sticks or becomes damaged.
- Electrical contacts show signs of corrosion.
Check the wiring, connections and interior light bulb before replacing the switch.
Later Porsche 356B T6 and 356C models generally use a different switch, reference 64461560106.
Confirm the original switch and electrical connections before ordering.
Porsche 356 Door Contact Switches & Interior Lighting Components
The door contact switch is an important component of the Porsche 356 interior lighting system, automatically controlling the courtesy light as the door opens and closes.

Porsche Interior & Compartment Lamps | Precision Lighting for Every Detail
Interior and compartment lamps illuminate your Porsche’s cabin, footwells, storage areas, and luggage compartments — providing both practicality and luxury. These lights enhance visibility inside the vehicle at night while contributing to Porsche’s refined interior ambience. Over time, however, bulbs and fittings can fade, fail, or lose clarity, diminishing both function and style.

Each product is engineered for precision fitment, durability, and superior brightness — offering a perfect balance between performance and design.
