The membrane switch is a revolutionary electronic component that combines light, machinery, and electricity, transforming the appearance and structure of electronic products. Unlike traditional discrete components, thin-film switches can easily replace buttons and perform operating system tasks with greater reliability. These switches possess exceptional waterproof, dustproof, oil-proof, and gas erosion resistance. Additionally, they offer stable and dependable performance, lightweight design, compact size, long lifespan, easy assembly, and the ability to wash the panel without damaging the text. Moreover, they come in a variety of vibrant colors, enhancing the overall aesthetic appeal. Despite these advantages, many individuals are unaware of the basic structure and principles of membrane switches. Join Ji Deoksung as we delve into this topic.
