Membrane Switch Design Guide.
2 Introduction Membrane switch technology has become a reliable front panel solution where environmental concerns or frequent cleaning are an issue. The sealed nature of the technology coupled with its reliability and ability to offer tremendous aesthetic fle xibility make it the solution of choice for many industries.
3 specify type styles, colors, and sizes of all copy. Artwork should be provided to us fo r all logos or special symbols. We use the latest version of Autocad with Autoscript to generate our drawings and artwork. It is helpful for customers to supply us with an Autocad DWG file, or as an alternate, a DXF or IGES file.
4 Ultraviolet Hardcoats The most durable hardcoats are those that are cured by exposure to ultraviolet light. These coatings are called UV hard-coats. Hardcoats can be selectively added to many of the materials to produce parts with a velvet textured background, and gloss or anti-glare windows.
5 switch. Standard tolerances should be +/- .015". Tolerances of +/- .010 " can be held on critical dimensions such as the perimeter or cutouts. Hole center to hole center tolerances of +/- .005" can be held. Tolerances on very large parts will be greater.
6 considered when specifying shielding requirements. Tail Exit Point Flexible membrane switches are connected by means of a flexible tail that is cut from the circuit material. We have a great deal of flexibility in selecting the exit point. The tail cannot exit under or within .
7 Creasing of Flex Circuits In many applications the tail of a membrane switch needs to be bent at or near the exit point. Extreme caution should be exer cised when bending flex circuits.
8 sense to consider polyester domes if the total dome usa ge per order is expected to exceed 2500. A drawback of polyester domes is that they tend to relax and lose their tactile feel at elevated temperatures and are not recommended for applications that will experience temperatures above 55 ˚ C (131 ˚ F).
9 -45 ˚ C to + 75 ˚ C (See notes on polyester domes) Life Cycle Testing Holland Nameplate performs life cycle testing to insure tha t our customers have a realistic expectation as to the typical number of cycles a particular design ca n endure.
10 that will have insertable legends. An oversized pocket is put behind this clear area so that the legend card can be inserted and seen through the window. The entire overlay has the same texture, which helps hide the fact that legends are being viewed through a window.
11 Always clean the surface before installing a membrane switch. If alignment is difficult, we recommend that you remove a small corner of the backing, align the membrane switch, stick the corner down, bend back the membrane switch and rem ove the rest of the liner.

22 Glossary Appendix D Actuation Forc e- The maximum force measured pr ior to or including the point at which keypad contact closure is achieved. Alodine- A chemical conversion process that oxidizes alum inum to form a non-porous aluminum oxide. Referred to as “poor-man’s anodizing” because it is less costly and not as durable as anodizing.
