Horn contact ring
This original Porsche steering wheel electrical contact component forms part of the horn circuit, helping provide the contact path needed for horn operation through the steering wheel assembly.

Fits:
Porsche 911 / 912 1965 - 1973

Diagram ref no 31

This part is used within the steering wheel / steering column horn contact assembly on selected early Porsche 911 and 912 models.

What This Part Does / Functions
•  
Provides an electrical contact path for the horn circuit
•  Allows horn operation through the steering wheel / horn button assembly
•  Maintains contact while the steering wheel turns

Why Replace This Part?
The horn contact ring is a small but important electrical part. Over time, the contact surface can become worn, dirty, corroded or damaged. It may also be missing or incorrectly fitted after previous steering wheel, horn button or column repairs. A faulty contact ring can cause intermittent horn operation, no horn function, poor contact or unreliable electrical continuity.

Replacing it with an OE Genuine Porsche horn contact ring helps restore the correct factory horn circuit and steering wheel fitment.

Common Symptoms of a Faulty Horn Contact Ring
•   Horn does not work
•   Horn only works intermittently
•   Horn works only at certain steering wheel positions
•   Poor or inconsistent horn button response
•   Corroded or worn contact surface
•   Damaged or missing contact ring
•   Incorrect aftermarket contact plate fitted
•   Fault found during steering wheel or horn button repair.

When to Replace This Part
•   If the horn contact ring is worn, corroded or damaged
•   If horn operation is intermittent or unreliable
•   During steering wheel removal or replacement
•   During horn button or horn circuit repair
•   During steering column restoration
•   If the original contact ring is missing
•   When replacing incorrect steering wheel hardware
•   When restoring the vehicle with OE Genuine Porsche electrical parts.

Where It Fits on the Car
This part fits in the steering wheel / steering column horn contact assembly. It forms part of the electrical contact system that allows the horn button to complete the horn circuit.

Correct installation is important to ensure reliable horn operation and avoid unwanted horn activation or loss of contact.

About Steering Wheels Parts

Porsche Steering Wheel Parts | Precision Components for Control & Performance

The steering wheel is the most direct connection between driver and machine — delivering precise control, tactile feedback, and the distinctive Porsche driving experience.
