Nangona kukho iindlela ezahlukeneyo zokuyila iikeypad zerabha zesilicone-rubber, uninzi lwazo lunefomathi efanayo equlathe izinto zerabha zesilicone ezijikeleze iswitshi ye-elektroniki embindini. Emazantsi ezinto zerabha zesilicone kukho izinto eziqhuba umbane, ezifana nekhabhoni okanye igolide. Ngaphantsi kwezi zinto eziqhuba umbane kukho umoya okanye igesi engasebenziyo, kulandele iswitshi esidibanisa umbane. Ngoko ke, xa ucinezela iswitshi, izinto zerabha zesilicone ziyatshintsha, ngaloo ndlela zibangela ukuba izinto eziqhuba umbane ziqhagamshelane ngqo neswitshi esidibanisa umbane.

Iikeypad zerabha zesilicone nazo zisebenzisa iimpawu zokubumba ezicinezelayo zale nto ithambileyo nefana nesiponji ukuvelisa impendulo echukumisayo. Xa ucinezela iqhosha uze ukhulule umnwe wakho, iqhosha liya "kuvela" liphinde liphakame. Esi siphumo senza imvakalelo ethambileyo yokuchukumisa, ngaloo ndlela sixelela umsebenzisi ukuba umyalelo wakhe ubhaliswe ngokufanelekileyo.
