Manual starters are devices operated manually, offering straightforward 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.

Important Note: Manual starters do not break control circuits during power loss, meaning motors could restart automatically when power is restored. This may require safety considerations in certain applications.

• Safe and economical operation
• Compact size suitable for diverse applications
• 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 activates the starter drive (Bendix gear system) to engage 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 flywheel as the engine no longer requires the electrical spark to maintain operation.
