Shacman H3000 Steering Wheel Button

Left Steering Wheel Switch (Radio Player, LIN With Cruise Control)

The left‑hand switch module is the primary interface for audio system control and cruise management. It features six tactile buttons arranged ergonomically: volume +/‑, track forward/back, source/mode selection, and a multi‑function button for cruise control (set, increase, decrease). The Shacman H3000 Steering Wheel Button switch communicates via the LIN bus, sending commands to the vehicle’s body control module and engine ECU. Its backlit icons (white or green) are clearly visible at night, and the buttons are designed with a positive detent feel for confident operation while driving.

Right Steering Wheel Switch (Cruise Control, Equipped With Radio And Cassette Player)

The right‑hand switch module is dedicated to cruise control functions while also providing auxiliary radio controls. It includes dedicated buttons for cruise on/off, set/‑, resume/+, and cancel, allowing the driver to engage and adjust speed without moving their hands from the wheel. Additionally, it offers secondary functions for radio tuning and cassette player controls (if equipped). The switch is pre‑wired with a compatible connector that plugs directly into the steering wheel harness. Its construction mirrors the left module in durability and backlighting, ensuring a uniform appearance and feel across both sides.

Seamless System Integration

Both switches are engineered to interface flawlessly with the Shacman H3000’s existing electronics. The left switch uses LIN protocol to communicate with the radio and cruise control modules, while the right switch sends signals via a dedicated wire pair. They are plug‑and‑play replacements for the original units, requiring no additional programming or calibration.

Durable Construction

Each button is made from UV‑stabilized ABS with a matte finish to resist wear and fingerprints. The internal gold‑plated contacts ensure low resistance and reliable switching over millions of cycles. The switch housings are sealed to prevent dust and moisture ingress, making them suitable for the harsh cabin environment.

Our Shacman H3000 Steering Wheel Button assemblies are 100% genuine OEM, guaranteeing the exact fit, electrical characteristics, and tactile feel of the original equipment. Unlike generic replacements, these switches are manufactured with the same tooling and materials as the factory parts, ensuring seamless integration with your truck’s infotainment and cruise control systems. This authenticity preserves your vehicle’s resale value and maintains the high standards of Shacman engineering.

The Shacman H3000 Steering Wheel Button modules are designed for quick installation. They come with the correct connectors and wiring tails, allowing a simple plug‑and‑play replacement without the need for splicing or adapter harnesses. This reduces installation time and minimizes the risk of wiring errors, getting your truck back on the road with full functionality in minutes.

Safety is paramount, and our switches are engineered to meet stringent automotive standards. The buttons provide positive tactile feedback, allowing drivers to operate them without looking away from the road. The backlighting is optimized for night visibility, and the switches are tested to withstand accidental spills, extreme temperatures, and vibration. Choosing genuine parts means you are investing in the safety of both driver and cargo.

We keep a consistent stock of both left and right Shacman H3000 Steering Wheel Button units, so you can order the exact side you need or replace both simultaneously for a uniform feel. Our competitive pricing and rapid shipping make it easy to maintain your fleet’s controls. With our support, you can ensure that every truck in your operation offers the same reliable, driver‑friendly interface that Shacman is known for.

Over time, steering wheel buttons can wear out due to frequent use, exposure to sunlight, or accidental spills. The most common symptoms are unresponsive buttons, intermittent function, or loss of backlighting. Our genuine Shacman H3000 Steering Wheel Button replacements restore full functionality, ensuring that you can control your radio and cruise control without distraction.

When replacing a faulty switch, it is important to disconnect the battery negative terminal to avoid any airbag or electrical issues. The steering wheel typically has access covers on the back; remove them to expose the switch mounting screws. Unplug the connector, swap the module, and reassemble in reverse order. Our switches come with the same connector as the original, so no harness modification is required.

The left switch’s LIN communication allows for advanced features like speed‑dependent volume adjustment and integrated cruise control with adaptive functions (if the vehicle is equipped). Our genuine switch ensures that these advanced features work correctly, as it is pre‑programmed with the correct firmware. Aftermarket switches often lack this capability, leading to reduced functionality.

The right switch provides dedicated cruise control buttons that are positioned for intuitive use. The “set” and “resume” buttons allow the driver to easily engage and adjust the set speed without fumbling for floor‑mounted pedals or stalks. This ergonomic design reduces driver fatigue and improves fuel efficiency by maintaining a steady speed on highways.

For fleet managers, standardizing on genuine Shacman H3000 Steering Wheel Button parts ensures that all drivers have the same control layout and feel, which is important for driver training and safety. Inconsistent switch operation can lead to confusion and potential errors. Our genuine parts provide a consistent experience across your entire fleet.

Both switches feature a matte black finish with white or green backlighting that matches the instrument cluster illumination. The buttons are slightly raised for easy identification by touch, and the symbols are laser‑engraved to prevent wear. This attention to detail ensures that your steering wheel looks and functions as good as new after replacement.

If you are upgrading from a base model without steering wheel controls, these switches can be retrofitted provided your truck has the necessary wiring harness and body control module support. Our team can advise on compatibility, but for most H3000 variants, the connectors are already in place. This is a popular upgrade for drivers who spend long hours behind the wheel.

The switches are designed to withstand temperatures from -40°C to +85°C, and they are tested to 100,000 actuation cycles. This durability is critical for trucks that operate in extreme climates or accumulate high mileage. By using genuine Shacman H3000 Steering Wheel Button components, you can be confident that they will last the lifetime of the vehicle.

Left Steering Wheel Switch (DZ97189584587) – Operating voltage: 24V DC (via LIN bus). Current consumption: 20mA (idle), 50mA (active). Button layout: 6 buttons with rubber dome contacts. Backlight: white LED, dimmable via vehicle dimmer. Connector: 8‑pin mini‑AMP, compatible with the original harness.

Right Steering Wheel Switch (DZ97189584586) – Operating voltage: 24V DC (direct switch inputs). Current rating: 50mA per button. Button layout: 4 dedicated cruise control buttons plus 2 auxiliary audio buttons. Backlight: white LED. Connector: 6‑pin mini‑AMP. Both switches are housed in PA66‑GF30 flame‑retardant material.

Each switch has been tested to withstand over 1,000,000 mechanical operations and 500,000 electrical cycles at rated load. The contact material is gold‑plated stainless steel to ensure low contact resistance (< 50 mΩ) and excellent corrosion resistance. The operating force for each button is 4.5 N ± 0.5 N, providing a satisfying tactile click.

The switches are E‑marked (ECE R10) for electromagnetic compatibility, ensuring they do not interfere with other vehicle electronics. They also meet the flammability standard UL94 V‑0 and have an IP54 rating for dust and splash resistance, making them suitable for the cab environment.

Both modules are supplied with the original Shacman packaging, including part number labels and installation instructions. The package contains the switch module, mounting screws (if required), and a small wiring harness adapter for certain retrofit applications (check vehicle compatibility).

For vehicles equipped with a cassette player, the right switch’s auxiliary buttons can control tape deck functions (rewind, fast‑forward, eject) when the appropriate head unit is installed. Our genuine switch ensures that these legacy functions remain operational, preserving the full capability of the factory audio system.
