Txawm hais tias muaj ntau txoj hauv kev los tsim cov keypads silicone-roj hmab, feem ntau muaj cov qauv zoo sib xws uas muaj cov khoom siv roj hmab silicone nyob ib puag ncig lub qhov hloov hluav taws xob hauv nruab nrab. Hauv qab ntawm cov khoom siv roj hmab silicone yog cov khoom siv hluav taws xob, xws li carbon lossis kub. Hauv qab cov khoom siv hluav taws xob no yog lub hnab cua lossis roj inert, ua raws li qhov sib cuag ntawm qhov hloov. Yog li, thaum koj nias rau ntawm qhov hloov, cov khoom siv roj hmab silicone deforms, yog li ua rau cov khoom siv hluav taws xob sib cuag ncaj qha nrog qhov sib cuag ntawm qhov hloov.

Cov keyboards silicone-roj hmab kuj siv cov khoom siv compression molding ntawm cov khoom mos thiab zoo li daim txhuam cev no los tsim cov lus teb tactile. Thaum koj nias rau ntawm tus yuam sij thiab tso koj tus ntiv tes, tus yuam sij yuav "dhia" rov qab los. Qhov cuam tshuam no tsim kom muaj kev xav tactile me ntsis, yog li qhia rau tus neeg siv tias nws cov lus txib tau sau npe kom raug.
