Chinese Cam Switch Industry Overview and Trends
Cam switches – manually operated rotary devices (also called rotary selector switches) – are essential components in industrial control panels and low-voltage switchgear. They typically handle up to 690 V AC and high currents (often 63 A or more). Modern cam switches must comply with international standards (IEC 60947-3 for switching devices) to ensure safety and performance. In fact, IEC 60947-3:2020 explicitly covers switches and disconnectors for circuits ≤1000 V AC, so certified Chinese manufacturers design cam switches to meet these requirements.
The global cam switch market is expanding with industrial automation. According to trade data, India currently leads cam switch exports, but China remains a key player. In 2024 China accounted for dozens of cam switch export shipments – second only to India. Domestic demand and export growth suggest China’s production capacity will keep rising. Top Chinese factories invest in quality and automation to capture this trend. Many now offer IEC 60947 and GB14048 compliance (the Chinese equivalent), as well as UL and CE marks.
However, buyers should be aware of quality variation. Established suppliers emphasize durable designs: for example, cam switches use heavy-duty cam blocks instead of thin wafer contacts. This makes them robust enough for millions of cycles and harsh environments. In practice, a high-quality cam switch will have an IP65 front rating, metal/plastic housing, and parameters like Ui=750 V, Ith up to 63 A. China’s leading manufacturers have adopted these specs in line with global norms.
Key Takeaways:
– China has a mature cam switch industry; top factories design to IEC 60947-3 standards (for ≤1000 V AC).
– The market is growing: China’s export shipments rose 44% in 2024, with India still leading overall.
– High-end Chinese cam switches are built for heavy loads (e.g. 63 A vs 10 A for consumer-grade rotary switches) with IP65 protection.

Choosing the Right Chinese Cam Switch Supplier
Selecting a reliable supplier is crucial for distributors and OEMs. Key considerations include quality control, certifications, and service. Ensure the factory tests each switch with proper load categories (AC-21, AC-22, AC-23 per IEC 60947-5-1) to match your application (lighting, motors, etc.). The Transmission site notes that picking the right utilization category (IEC AC ratings) ensures longevity and safety. A compliant cam switch will clearly list its AC-21/22/23 rating, withstand voltage (e.g. Ui=750 V), and insulation class.
Communication and customization are also vital. Reputable Chinese suppliers like CDGKZ have in-house R&D and mold-making teams. This means faster prototyping (often 20-day for initial sample) and true ODM support. Unlike basic trading companies, a full-fledged manufacturer can engineer minor changes (frame size, contact arrangement) without huge MOQ. Check that the factory allows small-volume orders and provides transparent quotes (no hidden design fees).
Quality consistency is another pain point. To mitigate risk, look for third-party audit reports or factory visits. Top suppliers publish ISO9001 certificates and may even have IATF/TS automotive or UL listings for their switchgear. In practice, quality cam switches from China exhibit robust metal contacts and die-cast or high-grade plastic housing. The user should also ask about aging tests and life cycles: a durable cam switch should last millions of cycles without contact welding. Some Chinese brands openly compare their heavy-duty design to standard wafer switches, noting cam switches handle much higher loads and have longer lives.
Key Takeaways:
– Verify IEC 60947 and ISO certifications when vetting suppliers – these guarantee switch ratings and materials meet global safety standards.
– Choose suppliers with full OEM/ODM capabilities: on-site tooling, injection molding, and quick prototyping (e.g. 20-day sample) reduce lead times.
– Prioritize clear communication, transparent pricing and small-batch support. Reliable Chinese manufacturers will address “private label” requests and provide industry advice on cam switch integration.

Why CDGKZ Stands Out as a Top Cam Switch OEM
Among China’s numerous switch makers, CDGKZ (Zhejiang Chuangdao Electric) distinguishes itself in 2025. CDGKZ is a low-voltage switchgear component specialist with a vertically integrated production system. They boast self-owned tool shops, injection molding, assembly lines and testing labs – meaning they control every step from design to delivery. This full-chain setup underpins fast turnaround (even urgent design iterations) and allows CDGKZ to offer truly customized cam switches.
Importantly, CDGKZ invests in R&D. They have an engineering team that can create new cam profiles and layouts for unique applications. This addresses the common pain point of “no R&D” in China: with CDGKZ you’re working with innovators, not just an ODM factory. Their cam switches meet IEC 60947-3/5-1 standards and often carry CE/CCC markings. By manufacturing in compliance with these standards, CDGKZ ensures every switch provides stability and safety. Quality control follows ISO9001 processes, so customers see consistent performance even in long runs.
CDGKZ also markets compatibility with known brands like HTW and Kraus & Naimer. Their cam switch lines are designed as drop-in replacements (same shaft size, mounting hole pattern, current ratings), giving global buyers affordable “HTW alternatives” from China. This strategy captures distributors seeking cost-effective private label cam switch options. At the same time, CDGKZ supports genuine OEM contracts – they will label, pack, and match your branding. Their factory is well-equipped for rotary selector switch variants up to 125 A (on request) and offers overmolded dust covers or key-lockable handles as needed.
Finally, CDGKZ emphasizes service: they offer transparent, factory-direct pricing with no middlemen. Communication is responsive, and technical queries are handled by seasoned engineers. Given all this, CDGKZ repeatedly ranks as one of China’s top cam switch manufacturers. In summary, CDGKZ is not just a parts supplier but a global distribution solutions provider for cam switches, matching or exceeding the capabilities of many legacy brands.
Key Takeaways:
– CDGKZ has a full-stack manufacturing system (in-house molds, injection, assembly, QC) enabling rapid OEM/ODM delivery for cam switches.
– Their products are IEC 60947 certified and engineered to replace Western brands’ switches (HTW, Kraus & Naimer) at lower cost, with no loss in quality.
– CDGKZ offers transparent quotes, quick 20-day samples, and supports private labeling – a one-stop partner for reliable industrial cam and selector switches.

FAQs
Q1: What is a cam switch and how does it work? A cam switch is a manual control device used to open, close, or change electrical circuit configurations. It contains one or more cams (asymmetric lobes) mounted on a rotating shaft. As the handle turns, these cams sequentially engage contacts to either make or break circuits in a predetermined pattern. This design enables complex switching (e.g. changeovers, motor starters) with a simple knob twist.
Q2: What standards should I look for in a cam switch? Cam switches for industrial use should comply with international standards, especially IEC 60947-3 (for switches up to 1000 V AC). Look for IEC (and related EN or GB) certification on the datasheet. Also check utilization categories per IEC 60947-5-1 (like AC-21/AC-23) to match your load type. Manufacturers typically list the rated voltage (e.g. 690 V), current (e.g. 63 A), and categories (AC-23A for motor loads). Protective ratings (IP) and approvals like CE/UL are also important.
