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.

Important Safety Note: Manual starters do not break control circuits during power loss, which means motors could restart automatically when voltage is restored.

• Safe and economical operation
• Compact size suitable for diverse applications
• Built-in overload protection for motor safety
• Available with various 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 transfers power from the battery to the starter motor, which then engages the vehicle's flywheel through a gear system (starter drive or Bendix).

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 external electrical assistance is no longer required.
