Thechosinthira cha piezoelectricIli ndi VPM (Versatile Piezoelectric Module) yokanikizidwa mu nyumba yachitsulo yolimba. Piezoelectric element module ndi zigawo zomwe zimapanga voltage poyankha kupsinjika kwa makina. Pogwira ntchito molingana ndi "piezoelectric effect," kuthamanga kwa makina (monga kupanikizika kuchokera chala) kumapanga voltage yomwe imatsegula kapena kutseka dera.
Motero, ikakanikizidwa, zinthu za kristalo za piezoelectric zimapanga kusintha kofanana kwa magetsi komwe kumatumizidwa ku bolodi la circuit kudzera muzinthu zolumikizira zoyendetsa, kutsanzira kutseka kwa switch youma, kudalira mphamvu ya piezoelectric kuti ipange kugunda kwa "pa" kwakanthawi komwe nthawi yake imatha kusiyana kutengera kuchuluka kwa kupanikizika komwe kumagwiritsidwa ntchito.
Mukakanikiza ndi mphamvu yokwera, ma voltage okwera komanso ataliatali amapangidwanso. Pogwiritsa ntchito ma circuitry ndi ma slider ena, kugunda kumeneku kumatha kukulitsidwa kapena kusinthidwa kuchoka pa pulse ya "pa" kupita ku pulse ya "off".
Nthawi yomweyo, ndi capacitor yomwe imayang'anira kusungira mphamvu, zomwe zimathandiza kuti batire ikhale ndi moyo wautali. Kutentha komwe kungagwiritsidwe ntchito kungakhale pakati pa -40ºC ndi +75ºC. Chinthu chachikulu ndi kusowa kwa zinthu zosuntha, monga masipiringi kapena ma lever, zomwe zimapangitsa kuti ikhale yosiyana ndi ma switch achikhalidwe amakina.
Kapangidwe ka switch imodzi kamakwaniritsa kutseka kwapamwamba (IP68 ndi IP69K) motsutsana ndi chinyezi ndi fumbi, zomwe zimapangitsa kuti ikhale yolimba ku kuwonongeka kapena zinthu zakunja. Popeza idagwiritsidwa ntchito nthawi zopitilira 50 miliyoni, ndi yolimba kwambiri kuposa ma switch amakina.
Chifukwa cha zinthu zimenezi, palibe mwayi woti ziwonongeke, zomwe zimawonjezera nthawi yogwira ntchito yawo. Ndipo apeza ntchito m'mafakitale osiyanasiyana. Angagwiritsidwe ntchito m'magalimoto, chitetezo, kukonza chakudya ndi malo odyera, m'mabwato apamadzi ndi apamwamba, mafuta ndi gasi, komanso m'makampani opanga mankhwala.
