Printable Area (1.5) Typ .059 The following provides guidelines for creating and insertion of legend cards for the membrane switch keypad assembly. Read all of the instructions prior to customizing and inserting the legend card. Pushbuttons • Using the borders on the insertable legend card as a guide, be sure characters on the card are Card (1.5) Typ .059 about 1.5mm (.059”) within these borders. This is the printable area. • Legend characters may be drawn, printed, etc. Be sure that application choice is completely Programmable Illuminated PB dry before inserting into membrane keypad assembly. Surface Sheet Instructions for Inserting Legend Card • Note correct orientation of insertable legend card. Insert card under surface sheet, and use caution 7 to avoid bending the membrane keypad assembly. Do not use pointed object to insert card, and do A B 9 C 6 8 D 5 3 4 2 P O 1 ST 0 not remove surface sheet. 3 C B 9 6 2 5 1 4 7 8 • Smooth any wrinkles or air pockets from surface sheet. Keylocks Protective Film Surface Sheet A • Align and center all legend characters within the squares of the surface sheet. • Peel off adhesive strip from the membrane keypad assembly. • The legend card is now firmly in place and cannot be removed. Adhesive Strip Rotaries • Detach the protective film. Connectors Recommended Connectors for 5 Pin Recommended Connectors for 8 Pin Straight: FCI Part No. SLW8S-5C7LF Right Angle: FCI Part No. SLW5R-5C7LF Right Angle: FCI Part No. SLW8R-5C7LF Slides Straight: FCI Part No. SLW5S-5C7LF PRECAUTIONS FOR HANDLING Tactiles • Assembly of legend card insert is handled by the customer. Therefore, we recommend to evaluate the finished product with the card assembled. • Nonilluminated products have a loophole on each key. It is possible to add optional illumination by installing appropriate LEDs. Legend card does not have loopholes. • To test proper electrical operation of switches, use of an electric buzzer is recommended. Tilt • Use an additional chattering prevention circuit for the switch circuit. • Do not operate switches with pointed objects (i.e. screwdrivers) to prevent perforation of film overlay. Touch • Use an FPC connector that corresponds to the printed circuit. Contact factory for suitable connectors. L • During assembly and installation of legends place devices on a level, sturdy surface. We do not recommend assembly and installation of device using a free hand or on a soft surface. • These devices contain adhesive that may emit noise. This does not affect product functionality. • Do not depress any switch areas during assembly/installation. • These membrane switches are built with air vents. Prior to installation, make corresponding holes to allow air vents to function. These holes should first be aligned with the membrane switch device, then made on the body of the final installation structure. Supplement Accessories Indicators • Do not fold, bend, or apply pressure to the product. Do not allow water or oil to penetrate through the air vents. Entry of any liquids through the air vents may cause contact failure.
