Manual starters are devices operated manually, designed for 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.

Note: Manual starters do not break control circuits during power loss, which means 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 in various enclosure options
• Low initial cost

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 the combustion process in petrol and diesel vehicles. Once the engine is running, the mechanism disengages the starter motor from the gear and flywheel as the engine no longer requires the electrical spark.
