Ignition Coil Vibrator

An ignition coil vibrator, also known as an ignition coil contact breaker, is a component used in older ignition systems of internal combustion engines. It is responsible for generating the high voltage needed to create a spark in the spark plugs, which ignites the air-fuel mixture in the engine's cylinders.

The ignition coil vibrator consists of a coil of wire wrapped around an iron core. When the ignition switch is turned on, a low voltage current flows through the primary winding of the coil. This creates a magnetic field around the iron core.

The ignition coil vibrator also includes a set of contact points, which are connected to the primary winding. These contact points open and close rapidly, interrupting the flow of current through the primary winding. This action causes the magnetic field to collapse and generate a high voltage in the secondary winding of the coil.

The high voltage produced by the ignition coil vibrator is then sent to the distributor, which distributes the voltage to the correct spark plug at the right time for ignition.

It's important to note that ignition coil vibrators were commonly used in older vehicles, particularly those with points ignition systems. However, modern vehicles typically use electronic ignition systems, which do not require an ignition coil vibrator.
