Manual starters are devices operated manually, offering simple 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.

• Safe and economical operation
• Compact size suitable for diverse applications
• Overload protection for motor safety
• Available with various enclosure options
• Low initial cost solution

Manual starters do not break control circuits during power loss, which means motors could restart automatically when voltage is restored. This requires careful consideration in safety-critical applications.

When the engine is activated (via stop/start button or traditional key), an electrical signal is sent to the starter solenoid. This component directs power from the vehicle's battery to the starter motor, engaging the starter drive (Bendix gear system) with the engine'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 flywheel as the engine no longer requires the electrical spark.
