Silicone keypads are widely used in remotes, phones, instruments and automotive controls.
Material: hardness typically ranges 40-70 Shore A, with UV-resistant formulas for outdoor use.
Conductivity: carbon or gold pills, or conductive coating. Gold offers lower resistance and longer life.
Printing: legends via silk-screen, pad printing or laser, with multi-color and backlight options.
Tooling: mold design depends on key count, travel and tactile feel requirements.
Production: consistent curing and demolding are key to uniformity. Partner with an experienced factory.
Regarding feel, another key parameter is rebound — the speed and force of the key returning after press. Conductive silicone keypads balance feel and life by tuning carbon pill size, silicone hardness, and key thickness, refined during sampling.
In mass production, fully automatic molding machines, in-mold auto ejection, and inspection fixtures ensure consistent feel and stable conductivity per batch. Note your tactile requirements (actuation force, travel, rebound) on the drawing and we customize tooling and compound accordingly.
