Porsche - a sports car manufacturer that has "raceborn" in its DNA. The perpetual aspiration of lightweight construction and sporty driving is therefore embedded in every development.

With the historic ignition starter switch, Porsche has developed a homage to historic races and has set itself the task of preserving the Porsche tradition of the "ignition key on the left". It was designed together with Studio F.A. Porsche Zell am See. Visually, it is reminiscent of the historic key head as used in the sports prototypes. For optimum stability and durability, it was milled from a single piece of aluminium. In order to protect the material, but also to recall the silver look of the aluminium bodies from the early days of Porsche motorsport, it was anodised in a clear finish. With 5 holes, finished with a Porsche logo on both sides, the historic ignition starter switch brings a touch of racing history to the Porsche sports cars of today.

About Ignition Switch

Ignition Switches – Reliable Starting Power for Porsche Vehicles

The ignition switch is a vital component in your Porsche’s electrical and starting system. It’s the gateway between the driver and the vehicle’s ignition, responsible for powering essential circuits — from the starter motor and fuel pump to dashboard electronics and accessories.

At Design911, we supply a full range of genuine and high-quality ignition switches for Porsche models, including 911, Boxster, Cayman, Cayenne, Macan, and Panamera. Each switch is precision-engineered to ensuring smooth operation, reliable starting, and long-term durability.

What Does an Ignition Switch Do?

The ignition switch controls the flow of electrical power throughout your vehicle. When the key is turned (or the start button is pressed), the switch engages different electrical stages:

  • Accessory position: powers interior systems such as the radio or windows.
  • On position: activates the engine’s control systems and dashboard electronics.
  • Start position: sends power to the starter motor to crank the engine.

In modern vehicles, the ignition switch may also interface with immobiliser systems or electronic control modules for added security.

Why Do Ignition Switches Fail?
Over time, ignition switches can deteriorate due to wear, heat, vibration, and moisture exposure. Common causes of failure include:

  • Worn electrical contacts leading to intermittent or no power.
  • Key cylinder wear causing stiffness or sticking when turning.
  • Internal short circuits from heat or corrosion.
  • Broken return springs preventing proper key position.
  • General mechanical wear after years of use.

Symptoms of a failing ignition switch include:

  • The engine not cranking or starting.
  • Electrical accessories failing to power on.
  • The key getting stuck in the ignition.
  • Flickering dashboard lights or intermittent electrical faults.

Why Replace a Faulty Ignition Switch?

A failing ignition switch can quickly escalate from an inconvenience to a breakdown or safety risk. Replacing it restores proper electrical control, ensuring your Porsche starts and runs reliably.

Benefits of replacement include:

  • Reliable engine starting and accessory power.
  • Elimination of intermittent electrical faults.
  • Improved safety and system reliability.
  • OEM-level compatibility and performance.
