Ngakhale pali njira zosiyanasiyana zopangira ma keypad a silicone-raber, ambiri ali ndi mawonekedwe ofanana okhala ndi zinthu za silicone raber kuzungulira switch yamagetsi pakati. Pansi pa zinthu za silicone raber pali zinthu zoyendetsera magetsi, monga carbon kapena golide. Pansi pa zinthu zoyendetsera magetsi pali mpweya kapena mpweya wosagwira ntchito, kutsatiridwa ndi switch contact. Chifukwa chake, mukakanikiza switch, zinthu za silicone raber zimasokonekera, zomwe zimapangitsa kuti zinthu zoyendetsera magetsi zigwirizane mwachindunji ndi switch contact.

Ma keypad a silicone-raber amagwiritsanso ntchito mphamvu zomangira zinthu zofewa komanso zofanana ndi siponji kuti apereke mayankho ogwira mtima. Mukakanikiza batani ndikutulutsa chala chanu, batanilo "lidzawonekera" mmwamba. Izi zimapangitsa kuti munthu amve ngati akugwira pang'ono, zomwe zimauza wogwiritsa ntchito kuti lamulo lake lalembedwa bwino.
