Membrane Switch Material Selection:
The two most widely used graphic materials are polycarbonate and polyester. polycarbonate comes in thicknesses of 0.127 – 0.762mm thick while polyester comes in thicknesses of 0.127 – 0.254mm.
Polyester has greater tensile strength than does polycarbonate, which often allows it to withstand millions of actuation before fracturing. Also, polyester has a greater resistance to a broad range of chemicals.
Polycarbonate is slightly easier to both print and emboss.
Graphic Design and Preparation
Blueprints – Provide drawings that clearly dimension all physical characteristics including color breaks and copy.
Colors – Identify colors by using Pantone (PMS) color number or a color sheet. It is important to supply the exact standard for which our color match will be evaluated.
Background – Dark backgrounds and light text will provide greater clarity and show less wear and dirt.
Artwork – It is possible for customers to supply useable artwork.
Borders and Outlines – Avoid outlines close to cutouts or outer edges.
Text – Block lettering provides the most legible copy. Try to use common fonts. When logos or symbols are used, it is best to supply film positives or accurate black and white artwork .
