Import 3 Buttons Membrane Switch With Lcd — Buy in wholesale FOB from Supplier in China

This three-button membrane switch with integrated LCD display is manufactured by Dongguan Chun Yip Electronic Technology in Guangdong Province, China. The interface combines tactile input with visual feedback through a liquid crystal display module bonded to a PET, PC, or PVC substrate. Circuit traces use PET silver or FPC copper technology, with connector pitch options of 2.54 mm, 1.27 mm, 1.0 mm, or 0.5 mm to match standard header spacing. The overlay supports full Pantone, RAL, or custom colour-chip matching for branded equipment interfaces.

The membrane construction employs pressure-sensitive adhesive layers from 3M, Luxking, or Nitto, selected for environmental resistance and peel strength on the target mounting surface. Embossing options include pillow or dome profiles, providing tactile feedback without mechanical switches. The PET silver circuit variant suits cost-sensitive consumer and industrial applications, while FPC copper offers lower resistance for longer trace runs or higher current requirements. Standard industry practice for similar three-position medical or industrial controls specifies actuation forces between 150 g and 400 g, though the buyer should confirm the exact force curve for this configuration.

Typical applications include medical device control panels, industrial automation interfaces, laboratory equipment, and commercial food-service machinery where washdown resistance and flat-sealed construction are required. The RoHS and REACH compliance, plus ISO 9001:2015 certification stated in the source, indicate environmental and quality-management adherence common to electronics suppliers serving EU and North American markets. Importers should confirm whether the LCD module carries separate CE or FCC certifications, as display subassemblies often require additional electromagnetic compliance testing beyond the membrane switch itself.

Dongguan Chun Yip Electronic Technology is located on Xingye 5th Street in Xiabian Village, Dongguan, Guangdong Province, 523850, China. The supplier holds a harbor trust tier on the platform, with a response rate of 0.00 percent and zero average response hours recorded, indicating no historical inquiry data is available. The listing does not state year of establishment, employee count, factory floor area, annual revenue, or named client references. No OEM/ODM capability claims are made beyond the flexible customisation options in the product description.

The supplier's stated certifications are limited to RoHS, REACH, and ISO 9001:2015. No IPC (Association Connecting Electronics Industries) membership, UL file numbers, or medical-device-specific quality registrations such as ISO 13485 are mentioned. Buyers should verify factory audit status, in-house versus outsourced LCD module assembly, and whether the company manufactures the complete assembly or sources the display from a third party. The address places the supplier within the Dongguan electronics manufacturing cluster, a region with extensive membrane switch and flexible circuit supply-chain infrastructure.
