An essential component during steering column refurbishment or classic Porsche restoration, this contact plate helps maintain dependable horn functionality while preserving the original fit and appearance.
What Does the Steering Wheel Column Contact Plate Do?
The steering wheel column contact plate forms part of the horn circuit within the steering column assembly.
Its functions include:
- Providing a continuous electrical connection between the steering column and steering wheel.
- Allowing the horn push to complete the electrical circuit when pressed.
- Maintaining reliable contact while the steering wheel rotates.
- Supporting consistent horn operation during everyday driving.
- Helping preserve the original functionality of the steering system.
Although simple in design, the contact plate is vital for dependable horn operation and safe vehicle use.
Why Does the Contact Plate Fail?
Over many years of service, the contact plate is exposed to constant movement and electrical load, leading to wear and deterioration.
Common causes of failure include:
- Wear of the electrical contact surface.
- Corrosion caused by moisture and age.
- Oxidation resulting in poor electrical conductivity.
- Damage during steering wheel removal or installation.
- Fatigue or distortion after decades of use.
- Dirt and grease contamination affecting electrical contact.
A worn contact plate often results in intermittent or complete loss of horn function.
When Should It Be Replaced?
Replacement is recommended if:
- The horn operates intermittently or not at all.
- Electrical contact is inconsistent while turning the steering wheel.
- The steering wheel or column is being restored.
- The original contact plate is worn, corroded or damaged.
- Replacing other steering column electrical components.
- Completing a concours-quality restoration.
Replacing the contact plate while the steering wheel is removed is a straightforward preventative maintenance upgrade that can eliminate future electrical issues.
