An electric ignition starter switch is a device used in automotive systems to start the engine. Its primary function is to control the flow of electrical current from the vehicle's battery to the starter motor, which then cranks the engine to start it. The switch is typically located on the steering column or dashboard and is turned by the driver using a key.

After the engine has started, the key can be turned further to the "on" or "run" position, providing power to various electrical components while the engine is running.
In vehicles with push-button start systems, the traditional key and ignition switch are replaced by an electronic module. The function, however, remains similar, where the push button acts as a switch to control the flow of electrical current to the starter motor.
It's important to note that a faulty ignition switch can lead to starting issues or cause the engine to stall unexpectedly. Regular maintenance and timely replacement of a worn-out switch can help ensure the proper functioning of the starting system.
