Waterproof Membrane Switch Overlay Panels Can Be Washed Without Damage To Characters
Membrane switch, also known as light-touch keyboard, adopts an integral sealing structure composed of flat multi-layers. The new type of electronic components is a fundamental change in the appearance and structure of electronic products. It can replace the keys of conventional discrete components and perform the tasks of the operating system more reliably.
