The Core Operating Principle
Mochine oa mantlha o itšetlehile ka thepa e ikhethang ea mercury joalo ka mokhanni oa tšepe oa metsi. Ka har'a matlo a mehele, matamo a manyane a mercury a na le likamore tse tiisitsoeng. Metal contact pins ho tloha shaft e potolohang e kenella matamong ana a mercury, ha likhokahano tse emeng li hokahana ka lehlakoreng le leng la matamo a tšoanang. Ha shaft e potoloha, lithakhisa li tsamaea ka har'a mokelikeli oa mercury, o sebetsang e le borokho bo tsoelang pele bo bolokang tsela ea motlakase ntle le ho hohlana ha letho-ho{4}}ho tiileng.
Mokelikeli ona{{0}o ipapisitseng le tsamaiso ea likhokahanyo e khethollang lireng tsa mercury slip ho tse ling tse tloaelehileng. Li-slip rings tsa setso li lula li roaloa ha li-brashi tsa k'habone kapa tsa tšepe li ntse li hohla lireng tse bilikang. Mercury e felisa khohlano ena ka ho feletseng kaha metsi a mercury a phalla le liphetoho tse potolohileng likhokahano tse tsamaeang ho e-na le ho li hanyetsa.
