Electronic Switch
The ignition switch is an essential electronic part of a vehicle. As the key is turned it triggers different systems. The first one activates electric accessories, while second turns on the ignition and fuel systems. The third turns the engine.
The ignition key from Mercedes is unique to each car and, when you insert it into your vehicle's ignition system, the electronic switch checks the key to verify that it's genuine. If it's valid it sends an alert to the steering lock (if your car has one) and other computer components to unlock the door. This is a great method to allow you to start your car quickly and easily -and even if have lost your keys, you'll still access the car without any trouble.
But, despite the fact that we enjoy the convenience of our ignition switches, they can create serious issues for our roads. If the ignition switch is malfunctioning, it may not be sending enough power to your vehicle's vital electrical components, or it could have missing connections that prevent your vehicle from starting.
One of the most typical symptoms of a defective ignition switch is that it won't start your car in any way. It's usually because the switch doesn't turn to the "on" position- which powers on fuel and ignition systems.
Another sign of a defective ignition switch is that the key won't go into the first position, where you can examine the dashboard for warning lights. These lights usually come on when you press the ignition button. They dim after your car is started.
In some cases the dashboard lights remain dark even after you turn the key to "on". This is due to the fact that the ignition switch will temporarily supply power to the fuel pumpand ignition systems if the key is switched to "on". However the switch will then shut off power when the key is removed.
You should contact an auto mechanic when you experience any of these problems. A professional can identify if the switch is malfunctioning or not, and the steps you can take to fix it.
