Manual starters are simple, user-operated devices for controlling equipment. They feature a button or rotary knob that mechanically opens or closes contacts to start or stop motors. Note that these starters don't break control circuits during power loss, which may cause automatic restart when power returns.

• Safe and economical operation
• Compact design for versatile applications
• Built-in overload protection for motor safety
• Available with various enclosure options
• Cost-effective initial investment

When the engine is activated (via stop/start button or key), an electrical signal is sent to the starter solenoid. This component transfers power from the battery to the starter motor, which engages the starter drive (Bendix gear) with the vehicle's flywheel.

The starter motor turns the engine to initiate combustion in petrol and diesel engines. 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.
