The remaining items do not have HS codes listed but fall within the same HS chapter for printed circuit boards and panels. The supplier’s top categories span Agriculture, Computer Keyboards, Electric Components, Touch Screen/LCD Monitors, and Light Emitting Diode.

Product Range and Specialties of Dongguan Chun Yip Electronic Technology

The catalogue covers a variety of membrane switch formats: metal‑dome actuation, waterproof multi‑key membranes, graphic overlay push‑button switches, and LCD‑window integrated keyboards. Industry standards for such devices typically reference IEC 61084 for functional safety and durability, with common performance targets of 1 × 10⁶ to 5 × 10⁶ actuations, IP‑67 ingress protection for waterproof models, and operating temperature ranges from - 20 °C to +85 °C. Materials regularly used include PET, PC, PVC, and flexible printed circuits with silver conductive ink or copper FPC traces. Buyers also look for colour‑fast printing, backlighting compatibility, and surface resistance of ≤10 Ω/sq for conductive layers.

Trade and Export Information - Dongguan Chun Yip Electronic Technology

China is a major exporter of membrane switch assemblies, supplying North America, Europe, and Southeast Asian manufacturers of consumer electronics, industrial control equipment, and automotive infotainment systems. The HS‑4 code 8534 covers printed circuit boards, panels and other electronic components, which aligns with the supplier’s PCB‑based membrane keyboards. Importers typically require CE marking, RoHS compliance, and often UL certification for safety‑critical applications. Shipping is commonly arranged in 20‑ft or 40‑ft containers with anti‑static packaging, and Incoterms such as FOB Shenzhen or CIF Shanghai are standard. Export documentation includes a commercial invoice, packing list, certificate of origin, and test reports confirming IEC 61084 compliance.

Sourcing from Dongguan Chun Yip Electronic Technology - Buyer Guidance

Buyers should request material data sheets that specify substrate type (PET, PC, PVC) and conductive ink composition, as well as test reports for actuation life, contact resistance, and environmental sealing (IP rating). Verification of CE, RoHS, and any UL or ISO 9001 certificates is advisable before placing orders. Typical minimum order quantities for custom graphic overlays range from 1 000 to 5 000 pieces, with lead times of 15‑30 days after artwork approval. Samples should be evaluated for key travel, tactile feel, and adhesion of the overlay under humidity cycling.

What types of membrane switches does Dongguan Chun Yip Electronic Technology offer?

The supplier lists metal‑dome switches, waterproof multi‑key membranes, LCD‑window integrated keyboards, graphic overlay push‑button switches, and capacitive touch membrane keyboards, covering both standard and custom formats. Each product is designed for integration into control panels, keyboards or display devices.

Is there an HS code associated with any of the products?

Yes, the Pcb Control Panel Switch Membrane Keyboard is recorded under HS code 8534.00, which applies to printed circuit boards, panels and similar electronic components. This code is used by customs to classify the product for import duties.

What material specifications are typical for the listed membranes?

Products are described as using PET, PC or PVC substrates combined with PET silver conductive ink or flexible copper (FPC) circuits, which are standard materials for durable membrane assemblies. These materials provide mechanical strength, chemical resistance and reliable conductivity.

Which certifications should a buyer request for these membrane switches?

Buyers normally request CE marking, RoHS compliance, and, where safety certification is needed, UL or IEC 61084 test reports to verify functional durability. Providing these certificates helps confirm that the switches meet international safety and environmental standards.

What are common performance specifications for these switches?

Industry specifications often require 1 × 10⁶ to 5 × 10⁶ actuation cycles, contact resistance ≤10 Ω, operating temperature - 20 °C to +85 °C, and IP‑67 protection for waterproof variants. Additional tests may include humidity cycling and adhesion strength of the overlay.

What are typical packaging and shipping methods?

Items are usually packed in anti‑static bubble wrap or sealed poly‑bags, placed in wooden crates or cartons, and shipped in 20‑ft or 40‑ft containers under FOB or CIF terms. Proper packaging protects the delicate conductive layers during transit.

What is the usual lead time and minimum order quantity?

Custom graphic overlay or keypad panels generally have a lead time of 15‑30 days after design approval, with minimum order quantities ranging from 1 000 to 5 000 units depending on size and complexity. Larger production runs can reduce unit cost and allow for tighter tolerances.
