Silicone rubber membrane for keypad
-30 .. + 180 ºC Esterline Interface Technologies

Elastomeric keypads provide long operational life and excellent tactile feedback. Elastomers (or silicone rubber keypads)offer an alternative look and feel to traditional polyester polycarbonate graphics. Relatively inexpensive and very reliable, elastomeric keypads provide long operational life and excellent tactile feedback. A number of enhancement and functionality opportunities exist--from legending and backlighting treatments to design shape, height, and texture options. We also provide a variety of abrasion resistant coatings and treatments to insure long life without noticeable wear.

Elastomeric Silicone Rubber Keypads easily interface with membrane switches, printed circuit boards and flex circuits utilizing polyester domes, stainless steel domes, carbon pills or non-tactile constructions.

Carbon Pill Elastomers integrate the electrical contact circuit into the rubber keypad that interfaces directly with
a polyester, polyimide or printed circuit board lower circuit.

Abrasion Resistant Coatings and Treatments are available in many varieties and can be applied to the surface of
elastomers to insure long life without noticeable wear.

Design Shape, Height, and Texture options are available with elastomeric keypads, offering the OEM customer several
choices to enhance the look of the input device.

Legending and Backlighting Techniques in a variety of treatments are available, including screen-printing and
laser etching.
