Custom Keypads

We specialize in the production of custom-built keypads, rubber keypads, and silicone keypads. If backlighting is required, we provide various backlighting styles ranging from LED (light emitting diode) to incandescent and LGF (light guide film), a new technology that produces a bright, evenly illuminated custom keypad, possessing a good tactile feel.

A custom keypad can be assembled using a variety of materials, including, but not limited to, epoxy, acrylic, polycarbonate, and silicone. We also co-mold silicone with metal frames for a rubber keypad that is both rigid and pliable, and ease the assembly into the final product.

Our innovative custom keypads can be manufactured to suit a variety of products ranging from audio/video equipment, calculators, MRI machines, medical equipment, and LCD watches.

Offering a range of styles such as dome, rubber, silicone, hard caps, and sheet metal, we have happily served a wide array of industries from aerospace to appliance and electronics. Contact Elite Sales & Technology today for more information about a premium custom keypad.


Silicone Rubber Keypad using Compression Molding & Silk Screening

Silicone Rubber Keypad using Compression Molding & Silk Screening

The pictured keypad is a simple silicone rubber keypad with opaque material and positive image printing. The ink used for the graphics is a silicone based ink so that it is bonded to the base material after post curing. A coating is applied to extend the life of the graphics if requested. We have several coatings for this function... Read More

Laser Etched Keypad with Polydome Array

Laser Etched Keypad with Polydome Array

This keypad is molded with translucent silicone material, screened with the required graphic colors, and spray painted with a silicone based black ink. The black ink is then removed by laser etching to reveal the graphics. This yields very attractive back lighted graphics without the flood lighting seen with back lit keypads with positive image or negative image silk screened graphics. The keypad is then sprayed with a protective coating to enhance the graphic life.... Read More

Ultra Thin Keypad Co-Molded with Silicone Rubber & Metal Frame

Ultra Thin Keypad Co-Molded with Silicone Rubber & Metal Frame

As the name suggests this keypad has Polycarbonate tops permanently adhered to a silicone base material. The graphics, in this case, are clear except for the green send and red end keys. When back lit these clear graphics appear white. However, when the backlighting is not on, the graphics appear black. This particular version called for a very attractive blue plastic key top. Other colors have been applied for other versions... Read More

Thermoplastic Polyurethane (TPU) Keypad

Thermoplastic Polyurethane (TPU) Keypad

This keypad has the soft feel of TPU (Thermoplastic Polyurethane). This TPU film is formed using a co-molding process with silicone rubber. It is similar to IMD (In Mold Decorating) but has a softer feel than is available with PET films generally used in IMD keypads. TPU film cannot be formed with deep draws like PET films used in IMD keypads. Thus they are ideal for thin keypads used in small hand held products. The TPU material has superior abrasion resistance and is resistant to chemicals and UV lighting... Read More
