The membrane switches are produced by "laminating" graphic overlays and switch circuit film layers. The layers are held together with 3M high performance adhesives. 3M high performance adhesives help prevent delamination of the layers and protect the switch circuit layers from outside contaminants. Product 3MTM Laminating Adhesives 467MP, 468MP, 7945MP, 7952MP, 7955MP, 7962MP, and 7965MP for Graphic Attachment Advantages Made with a moisture-stabilized liner that can be die-cut to many customer specifications used to laminate the graphics to the flexible circuit. Double linered adhesives (3M 7952MP and 7955MP) are available for pre-cutting openings in the adhesive. A polyester film with adhesives on both sides that acts as a dielectric spacer to separate and bond the top and bottom switch circuit layers.
