Manual starters are devices operated manually, designed for simple and straightforward operation without requiring expert intervention. These starters feature a button or rotary knob that enables users to turn connected equipment on or off through mechanical linkages that open or close contacts.

• Provides safe and economical operation
• Compact size suitable for diverse applications
• Includes overload protection for motor safety

When the engine is activated (via 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, activating it along with the starter drive (Bendix gear system).

The starter motor engages the vehicle's flywheel, cranking the engine to initiate the combustion process in both petrol and diesel vehicles. Once the engine is running independently, the mechanism disengages the starter motor from the gear and flywheel as the engine no longer requires the electrical spark to maintain operation.
