Membrane switch KEY
Tatu-dimensional membrane switch
Kazhinji, mabhatani ari pa membrane switch anongoshandisa mavara kuratidza chinzvimbo, chimiro uye saizi yemuviri wakakosha.Nenzira iyi, kurongeka kwekushanda kunogona kuonekwa chete nechiratidzo chemushandisi.Sezvo pasina ruzivo rwakakodzera rwemhinduro kuratidza kana chigunwe chakatsikirirwa mune inoshanda renji yekuchinja kuita shanduko,
Nekuda kweizvozvo, kuvimba kwekutarisisa kwemuchina wese uye nekukurumidza kwekushanda kunokanganisa.Rudzi rwemembrane switch inoita kuti switch kiyi muviri ibude zvishoma, yakakwira zvishoma pane pani kuti iite matatu-dimensional chimiro, inonzi matatu-dimensional kiyi switch.Iko-matatu-dimensional kiyi haingogone kutsanangura nemazvo huwandu hwemuviri wakakosha, kuvandudza kukurumidza kwekuzivikanwa, kuita kuti kubata kweanoshanda kunzwisisike, asi zvakare kuwedzera kushongedza kwechimiro chechigadzirwa.Kugadzirwa kwekiyi ine mativi matatu kunofanirwa kuitwa mudanho rekugadzira repanera Kurongeka, nemaburi ekugadzirisa maburi ekuisa chaiyo panguva yekutsikirira mold, uye kureba kwematatu-dimensional protrusions hakufanire kudarika kaviri ukobvu hweiyo substrate.Kuti kuve nekunakisa kutaridzika kwechigadzirwa, maprotrusions eyakasimudzwa membrane switch anogona kuitwa mune akawanda akasiyana, uye anofanirwa kurongeka mudanho rekugadzira repaneru, nemaburi ekugadzira kuitira kuti ive nenzvimbo chaiyo kana mold ichidzvanywa. , uye matatu-dimensional convex Kureba kwekusimudza hakufanire kudarika kaviri ukobvu hwe substrate.Nekutaridzika kwezvigadzirwa zvakanaka, maprotrusions eiyo yakasimudzwa membrane switch inogona kuchinjwa nenzira dzakawanda.
