Suzhou Menhow Wins New Patent: Technological Breakthrough in Extending Keypad Life of Membrane Switches
2026-05-18
Recently, Suzhou Menhow has added a new utility model patent titled "A membrane switch Structure for Extending Keypad Service Life". Through structural innovation and process optimization, this invention effectively solves the long-standing industry pain points of traditional membrane switches, such as easily worn conductive inks and premature keypad failure, further consolidating the company's technological leadership in the field of electronic touch components.
With years of experience in the R&D and manufacturing of printed circuits, flexible printed electronic, flexible pressure sensor and silicone keypad, Suzhou Menhow has always focused on the needs of high-end application scenarios including automotive, medical, and industrial control. Traditional membrane switches, flexible pressure sensor suffer from wear caused by frequent pressing,where repeated contact between metal domes easily scratches the conductive ink, shortening product life and affecting equipment stability.
The innovative patented design adopts a layered stack structure,optimizing the layout of the conductive substrate, conductive ink, adhesive spacer, and panel. A hardened ink protective layer is added at the contact point between the metal dome and the conductive ink. This structure cushions the impact of pressing and isolates direct friction from the metal dome, significantly reducing conductive ink wear and greatly improving keypad durability. Meanwhile, the new process is compatible with existing production lines, requiring no major factory modifications and balancing performance upgrades with cost-effective mass production.
