This starter solenoid is an electromechanical switch designed to control the high-current power supply to the starter motor in diesel engines, generators, and heavy equipment. It features heavy-duty terminals for reliable high-current connections and a control terminal for low-current activation from the ignition switch. When energized, the solenoid closes the internal contacts to deliver battery power directly to the starter motor, ensuring fast and dependable engine starting. The robust metal housing provides durability and resistance to heat, vibration, and harsh operating conditions, making it suitable for automotive and industrial applications.
