Design Considerations For Rubber Keypads
If you next project requires a rubber keypad, Sigma 6 Electronics, Inc. will manufacture an elastomer keypad that will deliver a a�customa� look and feel at a very a�standarda� price.

Made from durable silicone rubber Rigid flex PCB, silicone keypads are available in either conductive or nonconductive configurations to suit any design requirement. The keypad may interface directly with a printed circuit board (conductive) or with a membrane switch or other type of switches (non-conductive).

Applications are limitless.

There are two basic types of rubber keypads:

INTEGRAL: One-piece construction incorporating the keys and the keymat. This type may be constructed in one or several colors, and with or without legends or other special features. This type of rubber keypad is designed to fit directly into a bezel, typically in hand held devices.

INNER: A keymat designed to act as a switching or spring layer between the keys and a PCB or membrane switch circuit. This type of design is now very common in full travel keyboards, and has replaced the traditional mechanical switch keyboard. Sigma 6as integral silicone keypads are offered with or without legends, and in solid colors or natural, translucent rubber. Translucent keypads are used for back lit applications. The keys may be field-lighted (solid legend on a translucent, lighted background) or reverse field lighted (illuminated legend on a solid background.

All Sigma 6 silicone keypads are compression molded to exacting standards. Molds may be single cavity tools for prototype or low volume production, or large, multi-cavity tools for high volume requirements. Sigma 6 Electronics will assist you in your design to find the most economical financial solution.

Rubber Keypads offer the design engineer a wide range of colors, shapes, and finishes to enhance the beauty and functionality of the product. Our rubber keypads are found in the most demanding applications worldwide. Rely on Sigma 6 Electronics, Inc. for the quality and reliability you demand flex PCB. Why trust your silicone keypad design to anyone else?
