Knob Switches: Precision Control and Qijia Electronics' Core Competence

We are Shanghai Qijia Electronics Co., Ltd., established in 2004. After more than two decades of development and accumulation, we have grown into a High-Tech Enterprise integrating the design, R&D, manufacturing, sales, and service of high-quality appliance switches. We are committed to establishing a professional and reliable brand image in the industry.

The knob switch (or rotary switch) is a vital part of our core product line. It is a fundamental component we provide to customers for achieving precise control and intuitive Human-Machine Interface (HMI).

I. Core Product Portfolio and Technical Strength

1. The Breadth and Depth of Qijia Electronics' Products

Our core product line, "shqijia," covers a wide array of AC and DC appliance switches, including micro switches, rocker switches, pushbutton switches, trigger switches, and the rotary switches (knob switches) featured in this article. We also offer AC and DC circuit board modules and controllers.

These high-performance components are widely applied in:

• AC and DC power tools and electric garden tools.

• Cleaning equipment and household appliances.

• Specialized fields like medical equipment (such as oxygen concentrators), generators, electric strollers, and water pumps.

We provide highly adaptable core component solutions to customers across various industries.

2. Technological Innovation and Standardization Contributions

In the realm of technology, Qijia Electronics has achieved fruitful results, currently holding over 60 various patents, including more than 10 invention patents. We have actively participated in the formulation and revision of numerous national and industry standards for appliance switches, continuously driving the technical standardization of the industry. These achievements have earned us multiple honorary titles, including "Shanghai High-tech Enterprise" and "Shanghai Specialized and Innovative Enterprise."

II. Knob Switch Operating Principles and Applications

Knob switches play a crucial role in countless applications due to their intuitive multi-position selection capability.

Operating Principle: The switch works by the user rotating the external knob, which drives the internal rotor contacts to sequentially engage with the fixed stator contacts, thus switching the circuit state and selecting the function position. This design features a clear Detent Mechanism, ensuring excellent tactile feel and feedback during operation.

Advantages of Our Products in Application:

• Multi-Position Selection: Our rotary switch products can execute complex circuit switching involving multiple poles and throws, making them ideal for selecting measurement ranges in instruments and operational modes on industrial control panels.

• High Reliability: Our switches are designed with a focus on stability and durability. Through rigorous material selection and precise manufacturing processes, we ensure that our switches can reliably withstand tens or even hundreds of thousands of rotational cycles.

III. Production Capacity, Quality System, and Custom Services

We are dedicated to providing stable, efficient product supply and outstanding quality assurance to our global customers.

1. Excellent Manufacturing Capabilities

In 2025, we opened our new, modern factory, which is supported by over 150 employees, more than 20 assembly lines, over 20 injection molding machines, and more than 40 automated equipment. This gives us an annual production capacity exceeding 80 million units and annual sales exceeding 100 million RMB.

In production, we incorporate advanced manufacturing technologies and feature an FFU cleanroom to ensure precise process execution. In recent years, we have implemented large-scale automation, significantly improving production efficiency and product quality consistency.

2. Internationally Certified Quality Assurance

Quality is the lifeblood of the enterprise. We have established a state-of-the-art switch testing center (laboratory) accredited by the US UL WTDP Witnessed Laboratory and fully compliant with the ISO 9001 Quality Management System. Our entire product line has successfully passed multiple international certifications, including:

• North America: UL, ETL

• Europe: TÜV, CE, SEMKO, CB

• Asia: South Korea KC, China CQC

These certifications ensure our products fully meet the market access requirements of diverse global markets.

3. Professional Customization and Development

We possess professional independent product and mold design capabilities, allowing us to provide customized development services based on individual customer needs and precisely matching diverse application scenarios.
