Genuine original product 3792-00225 Plastic Main Power Switch Electrical Control for King Long Buses

The Main Power Rocker Switch (Part No. 3792-00225) is a heavy-duty electrical switch specifically designed for medium and large Chinese-made passenger buses. It serves as the master power control unit, enabling drivers or maintenance personnel to manually cut off or supply auxiliary power to the vehicle’s electrical system. Widely used in instrument panel installations, this rocker switch ensures safe and reliable operation of bus electrical circuits during startup, shutdown, or emergency situations.

Engineered for durability and safety, it features flame-retardant materials, high vibration resistance, and an IP67-rated enclosure for protection against dust and water ingress. This switch is commonly installed in leading Chinese bus brands such as King Long, Higer, Yutong, ZhongTong, Golden Dragon, Ankai, and Shenglong, making it a standard component in domestic commercial transportation fleets.
