Manual starters are devices operated manually, designed for straightforward operation without requiring expert intervention. The starter includes a button (or rotary knob) that enables users to turn connected equipment on or off.

• Safe and economical operation
• Compact size suitable for diverse applications
• Overload protection for motor safety
• Wide choice of enclosure options
• Low initial cost

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

When the engine is activated (via stop/start button or traditional key), an electrical signal is sent to the starter solenoid. This component directs 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 vehicles. Once the engine is running, the starter mechanism disengages automatically as the engine no longer requires electrical assistance.
