In-house Certified/ISO 9001:2015

Four Quality Gates, One Reliable Product

Each stage is backed by documented procedures, trained personnel and calibrated instruments.

Stage 1

IQC

Raw materials and components are inspected on arrival. We verify material certifications, dimensional accuracy and electrical properties against our specifications.

Stage 2

IPQC

Automated 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

FQC

Every unit is tested before shipment. Key parameters including contact resistance, insulation resistance and switching operation are verified on 100% of products.

Stage 4

OQC

Packed 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.

KNOWLEDGE CENTER

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.
