Manual starters are simple, manually-operated devices that provide straightforward motor control without requiring expert intervention. These starters feature a button or rotary knob that mechanically opens or closes contacts to start or stop connected equipment.

• Provides safe and economical operation
• Compact design suitable for diverse applications
• Includes motor overload protection
• Available with various enclosure options
• Low initial cost solution

Manual starters do not break control circuits during power loss, which means motors may automatically restart when power is restored. This behavior requires careful consideration in safety-critical applications.

When the engine is activated (via stop/start button or ignition 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 independently, the starter motor disengages from the flywheel as the electrical spark is no longer required.
