A graphic overlay, or membrane switch overlay, is the outermost layer of the membrane switch assembly. It is the intuitive part of an electronic interface that connects the user to the machine, device, or equipment; and the part of the membrane switch which is visible to the user, graphically defining the locations of the keypads,and explaining the operation of the equipment. For these reasons, the graphic overlay plays a significant role in defining the user experience.
A well-designed graphic overlay makes a powerful first impression of your company and your equipment. The design of the membrane switch overlay will set your equipment apart from the competition by providing an unsurpassed user experience.
Not only must the graphic (membrane switch) overlay explain the operation of the equipment, it must satisfy aesthetic requirements, and more importantly, environmental and physical end-use application requirements.
