Shenzhen Zigeng Technology Co., Ltd. (Own brand: BONSDA) was founded in 2015 and is located in Pingshan District, Shenzhen. The company is a comprehensive electronic components and supporting services provider, integrating independent R&D and production of precision electronic components, agency distribution of international brands, customized processing of membrane keypad switches, industrial label customization, and supply of electronic accessories.
The company started with the R&D and production of precision metal domes (tactile switches / dome switches). After more than ten years of development, its business scope has gradually expanded to switch components, membrane keypad modules, industrial identification labels, and various electronic accessories, forming a business model driven by both in-house manufacturing and supply chain integration. Leveraging its own production facilities and long-term cooperative processing resources, the company operates over 5,000 square meters of production space, equipped with comprehensive precision stamping equipment and inspection instruments. With a mature mass production system, the monthly production capacity stably exceeds 50 million pieces.
The company's own brand, BONSDA, primarily produces metal domes, surface-mount dome sheets, and custom-shaped tactile switch domes. All products are certified under ISO 9001 quality management system, RoHS environmental standards, and SGS testing, fully complying with both domestic and international export requirements. The company possesses independent mold development capabilities and can precisely adjust key parameters such as actuation force, stroke, and thickness according to customer specifications, supporting the entire process from prototype sampling to mass production.
In terms of agency distribution, the company is an authorized distributor of South Korea's SUNGMUN, distributing products including encoder switches, slide switches, tactile switches, and DIP switches. Additionally, the company distributes imported domes from U.S. brand SNAPTRON, French brand Nicomatic, and various Japanese series. These imported products complement the self-owned BONSDA brand, addressing both conventional mass-production needs and demanding application scenarios, thus providing customers with a diverse range of selection options. All agency and distribution products are operated on a distribution basis.
In customized processing and supporting services, the company offers custom membrane keypad switch manufacturing, including membrane printing and circuit tracing, which can be flexibly integrated with either in-house or imported domes for various key switch modules. The company also provides industrial label customization solutions, including terminal identification labels and laminated labels, to meet product identification, traceability management, and durability requirements in electronics manufacturing. Furthermore, the company supplies complementary electronic accessories such as potentiometers, encoders, and connectors, helping customers streamline their procurement processes.
Quality is the company's foremost principle. Leveraging its in-house mold workshop and production system, the company offers 12-hour rapid prototyping and 48-hour batch shipping. Over a decade of process expertise has given the company mature technical experience in dome structure improvement and precision stamping, effectively addressing common industry challenges such as high thresholds for non-standard customization and extended lead times. Products are primarily applied in 3C electronics, smart wearables, home appliances, industrial control, automotive electronics, and medical equipment. The company has long served multiple listed companies and leading electronics manufacturing brands, building a solid industry reputation through stable quality control and reliable delivery capabilities.
Embracing globalization with an open mind, the company, as an official authorized distributor of South Korea's SUNGMUN in China, deeply integrates its advanced encoder switches, slide switches, tactile switches, and DIP switches — precisely connecting the sophisticated requirements of smart meters, industrial control, and ultra-thin consumer electronics with SUNGMUN's automated production line technologies. At the same time, by distributing imported domes from U.S. brand SNAPTRON, French brand Nicomatic, and various Japanese series, the company complements its high-performance product portfolio with premium global resources. The self-owned BONSDA brand and the represented international brands form a "dual-engine drive" — the former addresses conventional needs with volume production and customization, while the latter tackles technical challenges in harsh operating conditions, creating a "full-scenario, no-blind-spot" selection ecosystem for customers.
