Car switch: everything you need to know

The vehicle switch can refer to two different elements: the first is the ignition switch found on older gasoline powered vehicles, the second refers to the rev limiter that is activated during a specific phase of engine revs on vehicles.

🚗 How does a car switch work?

The term breaker can refer to many different things. Thus, it can represent 2 different elements:

• Speed ​​limiter switch ;
• Ignition switch.

The first is the hydraulic hammer model, present on all vehicles, but mostly on high power or tuned vehicles. It will start when the engine enters a phase of strong enough work.

Indeed, this will limit overspeeding in order to prevent valves out of the engine, don't panic. Their panic is due to their return spring, which at too high a speed stops working correctly and comes into contact with pistons.

In practice, this is an inertial contact that is present on the ignition rotor of a vehicle. Thus, at high engine speeds, the contact between the switch and the supply to candles.

The ignition switch is a mechanical part that is part of the ignition system and is found on older gasoline vehicles.

This allows a very strong electrical voltage to be produced at a level induction coil so it causes, by multiplying electrical power, a spark in the spark plug to start burning.

It is synchronized with the rotation of the motor and is started by it. This is especially due to ignition capacitor.

We are currently talking more about the first type switch because the ignition switch is no longer used on modern cars.

⚠️ What are the symptoms of a worn out car switch?

Modern breakers are maintenance-free and designed to last the life of your vehicle. Therefore, they are not wearing parts; they are not tested on vehicles during corrections or technical checks.

However, ignition switches on older gasoline vehicles can be worn and this wear shows up in several symptoms:

• Difficulty getting started : you will have to start over several times before your car starts to start well and allows you to start the journey;
• Excessive fuel consumption : since combustion is not going well, more fuel will be needed than usual;
• Loss of engine power : the engine can no longer warm up enough to offer the driver significant power when he depresses the accelerator pedal;
• Jerks and breaks : Poor combustion and suboptimal temperatures can cause engine stalling or jerking when driving.

👨‍🔧 How to turn on the switch on the machine?

If you are a fan setting, you can make changes to the switch of your car. Since the breaker is activated during one of the phases when the engine speed is very high, you can postpone these phases by increasing the power of your vehicle's engine.

To improve the performance of your vehicle's engine, you can perform reprogramming calculator. This type of operation may damage the switch and you must inform your Car insurance to make sure you are always covered.

Moreover, this type of reprogramming is relatively expensive. Count between 400 euros vs 2 euros while larger upgrades can cost up to 5 000 €.

💰 What is the cost of replacing a breaker?

If you have an old gasoline car, such as a vintage car, you may need to replace the ignition switch, especially if you are experiencing the symptoms listed above.

As a rule, the ignition key is changed together with the ignition capacitor. The two parts are often sold as a kit at prices between 15 € and 80 €.

Thus, the switch on new and old cars is very different. Its role plays an important role in modern cars to keep your engine safe when it reaches high operating speeds. Since it is not a wearing part, it does not require special maintenance or periodic replacement.
