Easy To Assemble Membrane Switch Overlay Moisture Proof And Long Service Life

Easy To Assemble Membrane Switch Overlay Moisture Proof And Long Service Life​

Membrane switch has good waterproof, dustproof, oilproof, harmful gas corrosion resistance, stable and reliable performance, light weight, small size, long life, convenient assembly, the panel can be washed without damage to the characters, rich in color, beautiful and generous, etc. advantage. Make your products more contemporary with membrane switches. The main type of membrane switch The membrane switch panel is a rigid or flexible printed circuit board as the substrate, with touch or no touch buttons installed, and then covered with plastic (polycarbonate PC, polyester PET, etc.) printed with colorful decorative patterns. Etc.) The electronic component composed of thin film panel, which integrates switch function and decorative function, is a new type of human-machine dialogue interface. The connection between the switch circuit and the whole machine can be completed by welding or plugging.

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.
