WG9100760100 37ZB1-36010 Truck Spare Parts Battery Switch Main Power Switch for Sinotruk HOWO FAW

The 37ZB1-36010 Manual Battery Main Switch (commonly known as the battery master disconnect or power cut-off switch) is a rugged, manually operated electrical isolation device designed for use in 24V heavy-duty commercial vehicles and off-road equipment. It allows drivers and technicians to physically disconnect the battery from the entire vehicle electrical system, providing essential protection against parasitic drain, electrical fires, and unauthorized operation.

Commonly found on Dongfeng, FAW Jiefang, Sinotruk HOWO, Shacman, Foton Auman, XCMG, SANY, and Golden Dragon buses, this switch is a fundamental safety component — especially for fleets operating in remote areas, mining zones, or during long-term storage.
