Reverse Switch WG2209280023 Sinotruk

Product Introduction

This Reverse Switch WG2209280023 is an OEM transmission control component exclusively designed for Sinotruk heavy-duty trucks (e.g., HOWO series). It features a corrosion-resistant brass hexagonal mounting body, a precision-machined stainless steel sensing probe, and a red spiral protective cap for the electrical interface. Manufactured to Sinotruk’s strict OEM tolerances, it is engineered to reliably detect the reverse gear position in the harsh mechanical environment of heavy-duty transmissions, resisting vibration, transmission fluid corrosion, and extreme temperature fluctuations.

Core Functions

1. Reverse Gear Position Detection: Utilizes a spring-loaded mechanical plunger to detect when the transmission is shifted into reverse, instantly triggering a low-voltage electrical signal.

2. Safety System Activation: Directly activates the vehicle’s reverse lights and audible backup alarm, providing critical visual and auditory warnings to surrounding personnel and vehicles during reversing maneuvers.

3. Sealed & Durable Construction: The hermetically sealed internal structure and brass housing prevent leakage of transmission fluid and ingress of dust/moisture, ensuring long-term reliability in high-vibration operating conditions.

4. Plug-and-Play Installation: The precision-machined mounting threads and standardized electrical interface match the original vehicle’s specifications exactly, allowing for quick and tool-friendly replacement without modifications.

5. OEM Calibration Compatibility: Precisely calibrated to the transmission’s shift mechanism stroke, ensuring accurate signal triggering without false positives or delayed response.
