Product Description
Product Introduction
This Exhaust Brake Switch WG9719584116 is an OEM electrical control component exclusively for Sinotruk heavy-duty trucks (HOWO 371/336, T5G, A7, SITRAK series). It features a rugged black ABS rocker switch housing with an embossed exhaust brake icon, precision internal copper contact terminals, and a plug-in PCB base with factory laser-etched part identification (ID:00243, WG9719584116/2). Designed for flush installation in the truck’s instrument panel switch panel, it adheres to Sinotruk’s OEM standards for electrical stability and mechanical durability, ensuring reliable operation in high-vibration, temperature-fluctuating cab environments.
Core Functions
-
Exhaust Brake Activation: Serves as the driver’s primary interface to engage/disengage the vehicle’s exhaust brake system, providing auxiliary braking force during downhill driving or deceleration to reduce wear on the service brake system.
-
Intuitive Operation: The embossed icon and tactile rocker feedback enable clear identification and operation, even when wearing work gloves, ensuring safe and accurate control during driving.
-
Stable Electrical Connection: High-conductivity copper internal contacts with silver plating ensure low contact resistance and corrosion resistance, preventing signal interruption or switch failure under long-term use.
-
Cab Environment Adaptability: The sealed switch structure prevents dust and beverage spills from entering the internal circuit; the high-temperature resistant ABS housing resists deformation from prolonged sunlight exposure in the cab.
-
OEM Direct Fit: Precisely matches the instrument panel switch slot dimensions and original wiring harness plug-in specifications, with standardized pin definitions for the exhaust brake control signal, supporting plug-and-play installation without wiring adjustment.
