Built for Global OEM Standards
Dongke Electric products are manufactured in our ISO 9001:2015 facility with UL- and TUV-certified in-house laboratories. Every unit passes four quality gates before it ships.
Four Quality Gates, One Reliable Product
Each stage is backed by documented procedures, trained personnel and calibrated instruments.
Stage 1 IQCRaw materials and components are inspected on arrival. We verify material certifications, dimensional accuracy and electrical properties against our specifications. | Stage 2 IPQCAutomated assembly lines are checked at every station. Regular line inspections, first-article checks and SPC monitoring detect and correct deviations in real time. | Stage 3 FQCEvery unit is tested before shipment. Key parameters including contact resistance, insulation resistance and switching operation are verified on 100% of products. | Stage 4 OQCPacked batches are re-checked before dispatch. Our team performs sampling inspections based on AQL standards, verifying packaging integrity and labeling accuracy. |
Quality You Can Trust | Dongke Electric operates a dual-accredited testing laboratory (UL + TUV) — a distinction shared by only a handful of manufacturers in our industry. | Trusted by Customers in 30+ Countries |
Difference Between a BLDC Motor Switch and a BLDC Motor Controller
A BLDC motor switch is mainly used as an operator interface for controlling a power tool, while a BLDC motor controller is an electronic drive unit responsible for controlling motor operation, current management and brushless motor performance.
| Feature | Motor Switch (ZT/JT Series) | Motor Controller (WS Series) |
|---|---|---|
| Main Function | User control interface | Electronic motor drive & control |
| Position | Trigger / Handle | Electrical control system |
| Speed Control | Basic (variable trigger) | Advanced (electronic regulation) |
| Motor Management | Limited | Full electronic control |
| Primary Application | Power tool user interface | Motor drive & protection |
Dongke offers both product lines for complete cordless power tool control solutions.
