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.

• Provides safe and economical operation
• Compact size suitable for diverse applications
• Includes overload protection for motor safety
• Available with various enclosure options
• Low initial cost compared to other starter types

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

When the engine is activated (via stop/start button or ignition key), an electrical signal is sent to the starter solenoid. This component directs power from the vehicle's battery to the starter motor, which activates the starter drive (Bendix gear system) to engage the 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 electrical assistance.
