When you turn the key in your car, what do you see? A switch assembly, that’s what. And if you’re like most people, it’s something you don’t really think about. But what does that switch assembly do? In this article, we will explore the basics of the ignition switch assembly and what it does. We will also discuss the dangers associated with this part of a car and how to fix it if it malfunctions.
What is the Ignition Switch Assembly?
An ignition switch assembly (ISA) is a component of the automobile that is responsible for starting the engine. The ISA typically includes a key, push button, and circuit board. In most cases, the key must be inserted into the ignition switch in order to start the car. If the switch fails, it can prevent the car from starting.
How Does it Work?
The ignition switch assembly is a car part that controls the start of the engine. It’s an important part of your car, because it allows you to turn the key to the “on” position and start the engine.
When Should I Replace My Ignition Switch Assembly?
If you have a car with a factory electronic ignition, the switch assembly is probably just fine. If your car has an electronic ignition system, however, the switch assembly may need to be replaced.
The electrical wiring in your car’s ignition switch assembly can over time become corroded and blocked. This can cause your car to not start or to require more effort than usual to start. In addition, if the electrical wiring in the switch assembly becomes damaged, it could also create sparks that could ignite gas or oil fumes inside your car.
If you notice any of the following signs that your ignition switch assembly may need to be replaced, please do not hesitate to bring your car into a mechanic for inspection:
-Your car does not start easily – even after trying different techniques such as turning the key several times while holding down the gas pedal
-You have had trouble starting your car in cold weather
-Your engine has been humming or knocking for some time
What are the Possible Causes of a Failed Ignition Switch Assembly?
A failed ignition switch assembly may be the result of a number of different reasons. Some examples include:
-A broken wire inside the ignition switch
-A worn or damaged switch
-A dirty or corroded keyway in the switch
-Unstable electrical connections between components inside the switch
