DZ97189584630 Combination Switch

The DZ97189584630 Combination Switch is a core control component for the electrical system of SHACMAN series heavy-duty trucks (including tractor trucks, cargo trucks, and dump trucks). It integrates multiple control functions-headlight switching, turn signal control, wiper/washer operation, and high-low beam adjustment-centralizing key vehicle electrical controls for convenient driver operation. This ensures clear operation logic, quick function switching, and reliable signal transmission-critical for driving safety in different scenarios (such as night driving, rainy weather, or turning). We've supplied this combination switch to over 50 SHACMAN after-sales service centers, heavy-duty truck maintenance workshops, and fleet management teams for 8 years. All user feedback confirms its stable performance: sensitive switching, clear gear positioning, no contact failure or signal interruption even under long-term high-frequency use (10-15 times per driving hour), effectively avoiding functional failure of vehicle electrical systems caused by component defects.

We use high-quality materials and precision manufacturing technology for production: the shell is made of flame-retardant ABS plastic (high-temperature resistant and impact-resistant), the internal contact uses silver alloy (low contact resistance and wear-resistant), and the wiring terminal adopts tin-plated copper (anti-oxidation and stable conduction). The installation interface, fixing hole positions, and wire harness connector fully match the original SHACMAN electrical system (such as X3000, M3000 models), ensuring seamless installation without modification. It can withstand harsh working conditions-such as cab temperature changes (-40℃ to 85℃), frequent toggle force (30-80N), and dust/rainwater erosion-and no issues like shell cracking, contact oxidation, or terminal loosening occur. Replacement is straightforward: no need to modify the vehicle's wire harness, just disconnect the connector of the old switch, remove the fixing bolts, install the new switch in the correct orientation, tighten the bolts, and reconnect the wire harness. Before leaving the factory, we conduct strict tests: contact resistance test (≤50mΩ), durability test (300,000 cycles of switching without failure), and environmental adaptability test (stable performance under extreme temperature and humidity)-ensuring reliable quality.

Product Model: DZ97189584630

Applicable vehicles: SHACMAN series heavy-duty trucks (X3000, M3000, L3000) with original SHACMAN electrical system

Type: Combination switch (flame-retardant ABS shell + silver alloy contacts + tin-plated copper terminals)

Function: Integrate headlight switching, turn signal control, wiper/washer operation, high-low beam adjustment

Material: Shell (flame-retardant ABS plastic); contacts (silver alloy); terminals (tin-plated copper)

Installation: Direct replacement-matches original electrical system installation interface and wire harness connector

Working conditions: Working temperature -40℃ to 85℃; toggle force 30-80N; contact resistance ≤50mΩ; service life ≥350,000 km

1.Integrated multi-function control: Integrates headlight, turn signal, wiper, and high-low beam functions in one switch, simplifying the cab control layout and reducing driver operation steps.

2.Sensitive and reliable switching: Silver alloy contacts and precision gear design ensure smooth switching, clear gear feedback, and response time ≤0.1 seconds-more reliable than ordinary combination switches with copper contacts.

3.Perfect fit for SHACMAN: Manufactured in strict accordance with the original SHACMAN electrical system design parameters, the installation interface, fixing hole spacing, and wire harness connector fully match the original part. No need for adapter brackets or wire harness modification during installation-saving maintenance time by 35% compared to universal combination switches.

4.Durable and safe: Flame-retardant ABS shell resists high temperature and impact, silver alloy contacts and tin-plated copper terminals enhance corrosion resistance and service life. The switch meets automotive electrical safety standards, with no short circuit or fire risk even in harsh environments, extending the overall service life to over 350,000 km.

This Combination Switch (Model: DZ97189584630) is exclusively designed for SHACMAN series heavy-duty trucks equipped with the original SHACMAN electrical system, including SHACMAN X3000, M3000, and L3000 models. It is not compatible with other SHACMAN models with modified electrical systems or non-SHACMAN heavy-duty truck brands (such as SINOTRUK HOWO, FAW Jiefang)-these vehicles have different electrical system structures, installation interfaces, or signal protocol requirements, so this combination switch cannot be installed or used normally.

Q1: Can this combination switch be used on SHACMAN trucks with modified electrical systems?

A1: No, it cannot. The structure and signal protocol requirements of modified SHACMAN electrical systems are different from the original ones-using it will cause mismatched installation or abnormal signal transmission, leading to failure of electrical functions (such as non-functional turn signals or headlights). You need to select the combination switch specially designed for modified SHACMAN electrical systems.

Q2: Why do some functions fail or switch intermittently after installing the new switch?

A2: First, check if the wire harness connector is fully plugged in (avoid loose connection or wrong insertion). If the connection is normal, inspect if the switch is installed in the correct orientation (ensure gear alignment with vehicle controls). If installed properly, check if the vehicle's fuse or relay is intact (replace if damaged). If the problem persists, the switch may have quality defects (rare for new products)-replace the switch directly.

Q3: How to maintain the combination switch to extend its service life?

A3: 1. Clean the switch surface regularly to remove dust and oil stains (avoid using water or corrosive cleaning agents); 2. Check the wire harness connector for looseness or oxidation every 20,000 km (wipe with dry cloth if oxidized); 3. Avoid toggling the switch with excessive force or frequent violent operation, preventing internal contact damage.

Q4: Is it necessary to replace the matching fuse together when installing the new combination switch?

A4: It is not mandatory, but recommended. The new combination switch works best with intact fuses-reusing aged or damaged fuses may cause short circuits or function failure. For optimal safety, inspect the relevant fuses and replace them if there are signs of melting or damage.
