Manual starters are simple, manually-operated devices for controlling equipment operation. Featuring either buttons or rotary knobs, these starters use mechanical linkages to open or close contacts, starting or stopping the motor.

• Provides safe and economical operation
• Compact design suitable for diverse applications
• Includes overload protection for motor safety
• Available with various enclosure options
• Cost-effective initial investment

Manual starters do not break control circuits during power loss, which means motors may restart automatically when power is restored. This requires special consideration in certain applications.

When activated (via stop/start button or traditional key), an electrical signal is sent to the starter solenoid. This component:

1. Transfers charge from the vehicle's battery to the starter motor
2. Activates the starter drive (Bendix gear system)
3. Engages the vehicle's flywheel
4. Cranks the engine to initiate combustion

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.
