Import 3*6 Keys Membrane Digital Control Switch — Buy in wholesale FOB from Supplier in China

This 3 by 6 keys membrane digital control switch from Dongguan Chun Yip Electronic Technology in Guangdong Province provides an 18-position input interface with tactile feedback and a claimed waterproof and dustproof design for industrial and commercial environments. The membrane construction typically employs polyester or polycarbonate substrate layers with silver or carbon conductive traces, though the exact material stack and trace specification are not stated in the source. The 18-key count in a compact 3x6 matrix suits control panels where space is constrained and sealed operation against moisture or particulate contamination is required.

The tactile response in membrane switches generally comes from metal dome or polydome actuators beneath the graphic overlay, with operating forces ranging from 150 to 400 grams depending on dome geometry and material. The source mentions support for various voltage and current specifications but does not list rated contact capacity, dielectric strength, or insulation resistance. Standard membrane switches handle 12 - 50 VDC at currents up to 100 mA for silver flex circuits, though higher current variants with copper flex or PCB backers exist. Buyers should request the electrical load rating and confirm whether the waterproofing meets a specific IP rating, as membrane technology can achieve IP65 or IP67 with proper bezel sealing but this is not verified in the listing.

Target applications include manufacturing equipment interfaces, building automation panels, medical device controls, and consumer electronics where a flat, easy-clean surface is preferred over mechanical keys. The customisable key layout allows adaptation to different languages or function sets without retooling. Integration requires attention to adhesive mounting specification and connector tail length for rear-panel wiring. Trade terms, minimum order quantities, and lead times are absent from the source and must be confirmed directly with Dongguan Chun Yip Electronic Technology.

Dongguan Chun Yip Electronic Technology is located on Xingye 5th Street in Xiabian Village, Dongguan, Guangdong Province, postal code 523850. The supplier holds a harbor trust tier designation. Both response rate and average response hours show zero activity in the available data, indicating limited or no platform engagement metrics rather than verified responsiveness. The Xiabian Village address places it within the Chang'an or Humen industrial ring of Dongguan, an area dense with electronics manufacturing and supply chain services.

No establishment date, employee count, factory certification, or client portfolio is disclosed in the source profile. The company name suggests specialisation in electronic components, but the listing does not confirm production capabilities versus trading operations. Buyers should request a business licence, factory audit capability, and sample evaluation before committing to volume orders. The absence of response metrics means direct outreach through the listed contact channels is essential to gauge actual communication reliability and technical support depth.
