The "rotor" head is attached to the top of the distributor shaft which is driven by a gear on the engine's camshaft and thus synchronized to it. This rotor is pressed against a carbon brush on the centre terminal of the distributor cap which connects to the ignition coil either through the top and wired directly to the coil in HEI systems, or via the centre terminal in points ignition systems and remotely connected to the coil.
The rotor is constructed such that the centre tab is electrically connected to its outer edge so that voltage coming in to the centre post travels through the carbon point to the outer edge of the rotor. As the camshaft rotates, the rotor spins and its outer edge passes each of the internal plug terminals to fire each spark plug.

The OE MATCH Rotor Arm is an OE-matching ignition system component designed for distributor-equipped Porsche engines. Mounted inside the distributor, the rotor arm rotates in sync with the engine and distributes high-voltage current from the ignition coil to the correct spark plug lead via the distributor cap. This ensures that each cylinder receives a spark at precisely the right moment in the combustion cycle.

Contact Breaker Point Set
Keep your classic Porsche ignition system performing at its
best with this OE Match Contact Breaker Points.
Manufactured to OE specifications, these precision-engineered breaker points
are designed to restore accurate ignition timing, reliable spark generation and
dependable engine performance.
Fits:
- Porsche 911 1965-1968 2.0L / 912 SWB (F)

As one of the key service components within a traditional distributor ignition system, the contact breaker points control the opening and closing of the ignition circuit, allowing the ignition coil to generate the high-voltage spark required for combustion. Correctly adjusted breaker points are essential for smooth starting, stable idle, responsive acceleration and efficient engine operation.
Whether you're carrying out routine ignition maintenance, rebuilding a distributor or restoring a classic Porsche to its original specification, these OE Match breaker points provide factory-quality fitment, dependable operation and long service life.
What Do Contact Breaker Points Do?
Contact breaker points are responsible for switching the ignition coil on and off in precise synchronisation with engine rotation.
Their primary functions include:
- Opening and closing the ignition circuit.
- Triggering spark generation at the ignition coil.
- Maintaining accurate ignition timing.
- Supporting smooth engine idle.
- Ensuring consistent combustion.
- Providing reliable engine starting.
- Working in conjunction with the distributor, condenser, ignition coil and spark plugs.
Accurate operation of the breaker points is essential for maintaining engine performance and fuel efficiency.
Why Replace Contact Breaker Points?
As mechanical ignition components, breaker points naturally wear through continual opening and closing during engine operation.
Common causes of wear include:
- Contact surface erosion.
- Electrical arcing. Incorrect point gap adjustment.
- Heat-related wear.
- Oxidation and corrosion.
- Weak contact spring tension.
- General age-related deterioration.
- High mileage.
Routine replacement helps maintain accurate ignition timing and reliable engine performance.
Symptoms of Worn Contact Breaker Points
Common signs that replacement may be required include:
- Difficult starting.
- Engine misfires.
- Rough or unstable idle.
- Poor acceleration.
- Hesitation under load.
- Reduced fuel efficiency.
- Loss of engine power.
- Inconsistent ignition timing.
- Increased exhaust emissions.
Replacing worn ignition points restores smooth running and helps protect other ignition system components from unnecessary stress.
Benefits
- Restores reliable ignition performance.
- Maintains accurate ignition timing.
- Improves engine starting.
- Supports smoother idle.
- Enhances throttle response.
- Helps improve fuel efficiency.
- Reduces misfires and hesitation.
- Excellent value replacement component.
Installation Recommendations
When replacing the contact breaker points, it is recommended
to inspect or renew other ignition service components, including:
- Distributor condenser.
- Distributor cap.
- Rotor arm.
- Spark plugs.
- Ignition leads.
- Ignition coil.
- Distributor shaft for wear.
- Distributor advance mechanism.
After installation, the breaker point gap and ignition timing should be adjusted according to the manufacturer's specifications to ensure optimum engine performance.
