Let our engineer teams help you assess your membrane switch design options. we will tailor your membrane switch and graphic overlay to fit the application and your specifications.

• Materials: Depending on the application and environmental requirements, Polyester and Polycarbonates are commonly used. Thickness ranges are .007" to .010". Blended materials and UV hardcoat surfaces are additional options.
• Selective Textured Surfaces : For hardcoats as well as aesthetic enhancement of the graphic overlay.Durable and surface printing. Finish Options: glossyor matte surface,3H scratch resistance
• Embossing: Embossing of the key pads for key location can be achieved by full key (pillow) pad embossment or rim embossment.
• Windows: Transparent and deadfront display windows for viewing LCD and LED displays.
• Termination: Tail termination is accomplished by snap fit connectors, solder tabs, or exposed silver tabs (.100" centers typical).
• Tactile Feedback: Stainless steel domes range from 8-20mm. Poly domes are embossed onto a polyester layer or circuitry.
• Shielding: Shielding from ESD/EMI/RFI can be accomplished by a layer of metallized polyester or by screening a layer of selective graphite ink.
• Backlighting: Tiantai offers several options for the various information readout devices available to fit customer requirements.
• Panel Cutouts: Die cut holes and access for mechanical switches may be incorporated into membrane switch designs.
• Back-Plates and Printed Circuit Boards: Available as a finished assembly with  membrane switches.
• Environmental Design: Applications subject to various degrees of chemical exposure, moisture or high humidity are engineered and constructed accordingly. Outdoor UV resistant ,UV cured inks ,printed with up  to  complicated process color.

• Tail: The connector tails on membrane switches are typically designed so that a “tail filler” is needed between the tail exit position of the switch and the edge of the part. For membrane switch applications where moisture exposure is expected, this tail filler can result in moisture traveling along the tail and into the system electronics.

         Tiantai can design a membrane switch with no tail filler and associated moisture path. This design features a continuous “gasket” backside adhesive perimeter.

• Graphic Design and Engineering Assistance:Minimize air gap without spacer dots,backside of overlay,eliminate air gap with optically clear adhesive. Full service art and engineering departments are ready to provide complete or partial assistance in the aesthetic design of graphic overlays and the engineering of correct switch construction for your application.
