Musiyano uripo pakati pebhatani rine mapini maviriuyebhatani rine mapini manairi muhuwandu hwemapini nemabasa awo.
Kazhinji, bhatani rine mapini mana rinoshandiswa pamabhatani ekudzvanya ane chiedza kana mabhatani ekudzvanya akawanda. Mapini ekuwedzera ari mubhatani rine mapini mana anowanzo shandiswa pakupa simba mwenje we LED kana kudzora mamwe ma switch contacts. Kuti musiyanise kana mapini acho ari ekupa simba LED kana kudzora mamwe ma contacts, munogona kuongorora chitarisiko chebhatani kuti muone kana rine chiedza kana kutarisa mamaki ari padivi pemapini (mapini akanyorwa kuti “-” uye “+” ndeesimba re LED, nepo mamwe ari ekuwedzera ma contacts).
Kune mamwe marudzi e push button ane mabasa akasiyana. Semuenzaniso:
a. Bhatani rekudzvanya rine mapini matatu: Rudzi urwu rwebhatani rune pini imwe chete yakajairika, pini imwe yakajairika yakavharwa, uye pini imwe yakajairika yakavhurika. Kana ukabatanidza waya kune pini yakajairika uye pini inowanzovhurwa, bhatani rinowanzo vharwa uye rinobatana kana radzvanywa. Kana ukabatanidza waya kune pini yakajairika uye pini yakajairika yakavharwa, bhatani rinowanzo vhurika uye rinotyora kubatana kana radzvanywa.
b. Bhatani rekudzvanya rine mapini matanhatu: Iri bhatani rine mapini matatu rine mabasa maviri. Mapini ekuwedzera anopa dzimwe sarudzo dzekudzora kana mikana yekubatanidza. Chimwe chiitiko ndechekutibhatani rine mapini maviri rine chiedza chakavhenekerwa uye mamwe macontact ekudzora.
c. Bhatani rekudzvanya rine mapini mashanu: Kazhinji, bhatani rine mapini mashanu ibhodhi rine mapini matatu rine LED.
Ehe, kune mamwe marudzi akawanda emabhatani aripo. Kana uchida kudzidza zvakawanda, ndapota inzwa wakasununguka kuaverengataura nesunekudzvanya pano. Tinokutendai nekutarisa!
