Membrane Switches

Most membrane switches include at least an overlay, spacer, circuit (blank or functional) and adhesive layers. Shielding layers and/or features may also be added. The components may be ordered as an assembly or as stand-alone parts. Price: 5-10 pieces start at $2500 (price may increase depending on complexity).

Lead Time: 10 business days or less for most membranes. Materials: Standard stocked materials for the circuit layer are .005” and .007” polyester. Overlays are typically a velvet-textured polycarbonate, .005" to .010" thick. Spacers and adhesives are normally made from 3M spacer and adhesive stock, various thicknesses. Other materials may be available upon request.

Size: Maximum part size (including the tail) is 11” x 17”.

Traces: .015" trace widths on .025" centers are the smallest we can print (1mm pitch tails are the smallest we will provide for prototypes). Circuit Inks: CI-1001 Silver ECM Ink, CI-2001 Carbon ECM Ink, DI-7502 Dielectric ECM Ink and DI-7503 Dielectric ECM Ink.

Protection: Dielectric printed over any exposed trace, particularly on the tail, is the default design. .002” mylar laminate is available as an alternative to dielectric for trace protection.

Crossovers: Available for circuits that require two layers of printed conductive ink.

Design files: Layout in AutoCAD, graphic files in Adobe Illustrator (default). GM Nameplate maintains current or very near current versions of most design programs.

Remember: Turn-time is the driving factor behind the Instant Intaq membrane switch program. While we always strive for quality, membrane switch prototypes are guaranteed to serve as proof-of-concept parts, not as pre-production or production quality parts (i.e., the membrane assemblies will function and the overlay's colors will be reasonably close to specified colors; however, the functional membranes will not be built to meet exact specifications.)
