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

Important Note: Manual starters don't break control circuits during power loss, which means motors could restart automatically when voltage is restored - a critical safety consideration in some applications.

• Deliver safe and economical operation
• Compact size suitable for diverse applications
• Provide motor overload protection
• 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 charge from the vehicle's battery to the starter motor, activating it along with the starter drive (Bendix gear system).

The starter motor turns the engine's flywheel, initiating combustion in petrol and diesel engines. Once the engine runs independently, the mechanism disengages the starter motor from the flywheel as the electrical spark is no longer required.
