Custom PET PC Panel Overlay 3M Self Adhesive Window Tactile Membrane Switch Sticker

Product Overview:

Dignity manufactures a range of capacitive touch sensors (or switches) that provide the attractive modern look and feel, as well as the flexible UI of a touchscreen at a portion of the cost of a custom LCD touch module. Fully sealed behind a glass or plastic cover lens, with no moving components, and waterproofing, hard coating and other options available, capacitive touch sensors offer a reliable, durable, flexible and responsive alternative to traditional push button or membrane switches. Due to its resistance to scratching, chemicals, impacts and dust/debris, and its modern aesthetic, capacitive switching is achieving widespread use in industrial, medical, automotive and other industries.
