Iiswitshi ye-piezoelectricine-VPM (Versatile Piezoelectric Module) ecinezelwe kwisakhiwo sesinyithi esiqinileyo. Imodyuli yento ye-piezoelectric zizinto ezivelisa i-voltage ukuphendula uxinzelelo loomatshini. Ukusebenza ngokwe "isiphumo se-piezoelectric," uxinzelelo loomatshini (umz., uxinzelelo oluvela kumnwe) luvelisa i-voltage evula okanye evala isekethe.
Ngoko ke, xa icinezelwe, izinto zekristale zepiezoelectric zivelisa utshintsho olufanayo kwi-voltage oludluliselwa kwibhodi yesekethe ngezinto zokudibanisa eziqhubayo, zilinganisa ukuvalwa kweswitshi yoqhagamshelwano eyomileyo, zixhomekeke kwisiphumo sepiezoelectric ukuvelisa i-pulse emfutshane "kwimeko" enobude bayo obunokwahluka ngokuxhomekeke kubungakanani boxinzelelo olusetyenzisiweyo.
Xa ucinezelwe ngoxinzelelo oluphezulu, kwenziwa iivoltage eziphezulu nezinde. Ngokusebenzisa ii-circuitry ezongezelelweyo kunye nee-sliders, le pulse inokwandiswa okanye itshintshelwe kwi-pulse ye-"on" ukuya kwi-pulse ye-"off".
Kwangaxeshanye, ikwayi-capacitor enoxanduva lokugcina itshaja, nto leyo eyenza ukuba ikwazi ukwandisa ubomi bebhetri. Ubushushu bokusebenza bunokuba phakathi kwe--40ºC kunye ne-+75ºC. Uphawu oluphambili kukungabikho kwezinto ezihambayo, ezifana nezipringi okanye iilever, nto leyo eyenza ukuba ihluke kwiiswitshi zemveli zoomatshini.
Ulwakhiwo lwesitshixo esinye lufezekisa ukutywinwa okuphezulu (IP68 kunye ne-IP69K) ngokuchasene nokufuma kunye nothuli, okwenza ukuba ikwazi ukumelana nomonakalo okanye izinto zangaphandle. Zilinganiswe ukuya kuthi ga kwimisebenzi engama-50 ezigidi, azikwazi ukumelana nokutshayiswa, azingeni manzi kwaye zihlala ixesha elide kunezitshixo zoomatshini.
Ngenxa yezi mpawu, akukho thuba lokuguguleka, nto leyo eyandisa ubomi benkonzo yazo. Kwaye zifumene usetyenziso kwiindidi ezahlukeneyo zamashishini. Zingasetyenziswa kwezothutho, ukhuselo, ukucubungula ukutya kunye neendawo zokutyela, iinqanawa zaselwandle nezobunewunewu, ioyile negesi, kunye nomzi-mveliso weekhemikhali.
