Empa ka kakaretso, switch ea mochini e se nang litekanyetso tsa IP67 ha ea tšoanela libaka tse metsi haholo.
Li-switches tsa capacitive li ntse li hōla ka potlako, karolo e 'ngoe ka lebaka la tšebeliso ea tsona ho li-smartphone.Ha ho stroke, ha ho na likarolo tse tsamaeang.Capacitive touchscreen panels e na le insulator, e kang khalase, e koahetsoeng ka conductor e hlakileng, hangata indium tin oxide (ITO) kapa silevera.Hobane 'mele oa motho e boetse ke mokhanni oa motlakase, ho ama holim'a skrine ka monoana ho senya tšimo ea electrostatic ea skrine, e ka lekanyetsoang e le phetoho ea bokhoni.Mekhoa e fapaneng e ka sebelisoa ho fumana sebaka sa ho ama.
Empa capacitive touch switches ha se khetho ea pele bakeng sa lits'ebetso tsohle.Li-touchscreens tse ling tsa capacitive ha li khone ho sebelisoa ho bona menoana ka lisebelisoa tse thibelang motlakase tse kang li-gloves.Ka mohlala, mongobo o phahameng oa moea kapa marotholi a metsi a ka boela a kena-kenana le "touchscreen electrostatic field.Ka hona capacitive". ka kakaretso li-switches ha lia lokela ho sebelisoa haufi le matamo a ho sesa kapa li-whirlpools.
