When the driver activates the engine (either through a stop/start button or traditional key), an electrical signal is sent to the starter solenoid. This component transmits power from the vehicle's battery to the starter motor. The electrical current activates both the starter motor and the starter drive (Bendix gear system), which then engages with the vehicle's flywheel. As the starter motor rotates, it cranks the engine to initiate the combustion process in petrol and diesel vehicles. Once the engine is running, the mechanism disengages the starter motor from the flywheel as the engine no longer requires the electrical spark to maintain operation.

Manual starters are simple, manually-operated devices that provide basic motor control functionality. They feature either a button or rotary knob that allows users to start or stop connected equipment. The mechanical linkages in these starters open or close contacts to control the motor. Note that manual starters do not interrupt the control circuit during power loss, which means the motor may restart automatically when power is restored - an important safety consideration for certain applications.
