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

• Safe and economical operation
• Compact size suitable for diverse applications
• Overload protection for motor safety
• Wide selection of enclosure options
• Low initial cost compared to other starter types

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, engaging the starter drive (Bendix gear system) which connects with the vehicle's flywheel.

The starter motor cranks the engine to initiate combustion in petrol and diesel vehicles. Once the engine is running, the mechanism disengages the starter motor from the gear and flywheel as the engine no longer requires the electrical spark.
