INSERTABLE LEGEND CARDS
Instructions for Customizing Insertable Legends
The membrane keypad assembly comes with three insertable legend cards: yellow, gray and black.
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.
• Using the borders on the insertable legend card as a guide, be sure characters on the card are
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
dry before inserting into membrane keypad assembly.

PRECAUTIONS FOR HANDLING
• 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.
• 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.
• 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 installa-
tion of device using a free hand or on a soft surface.
• Do not fold, bend, or apply pressure to the product.
• 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.
Do not allow water or oil to penetrate through the air vents. Entry of any liquids through the air vents may cause contact failure.
