An intermediate starter switch, which is installed on vehicles with a manual transmission, prevents the vehicle from moving when the engine is started, thus increasing safety - the engine cannot be started until the clutch pedal is pressed.

Note: The layout of the starting system components is shown using a gasoline engine as an example. The layout of the components for a diesel engine is completely similar.
The starter relay, installed in the relay and fuse box, supplies power to the starter when it receives a signal from the electronic engine control unit. When current flows between A-B in the diagram shown in the figure, an electromagnetic field is generated, due to which the switch between CD is closed. The current flowing through the switch between CD is supplied to the starter.

The starter, mounted at the rear of the engine on the left side, rotates the crankshaft via the flywheel ring gear, causing the engine to start. The starter is equipped with a coaxial gearbox, which allows for high torque.
