SITRAK C7H MAX G7H SITRAK C9H SINOTRUK Parts Warp-plate Switch 812W25503-6035

The 812W25503-6035 Brake Request Switch (Warp-plate Switch) is a precision electrical component developed for SINOTRUK SITRAK C7H MAX, G7H, and C9H heavy-duty trucks. It is responsible for sending an accurate brake request signal to the truck’s control system, enabling correct interaction between the braking system, ECU/VCU, and other electronic control modules.

Manufactured with high-sensitivity internal contacts, reinforced terminal structure, and premium wear-resistant materials, this switch delivers fast signal response, stable transmission, and extended service life even under high vibration and intensive daily use.

Compared to standard aftermarket alternatives, it features stronger anti-interference performance and improved contact durability, ensuring consistent braking response in demanding environments such as long-distance haulage, mountainous roads, construction sites, and logistics operations.

Its OEM-matched structure and plug-and-play installation make it a perfect replacement for professional workshops and fleet maintenance teams.
