Itsindaicyuma gifunguza imizigoni igikoresho gihinduranya hagati y’icyuma gihagarika amashanyarazi n’icyuma gitandukanya amashanyarazi. Gifite igikoresho cyoroshye cyo kuzimya umuriro, gishobora guca umuvuduko w’amashanyarazi ugenwe n’umuvuduko runaka w’amashanyarazi, ariko ntigishobora guca umuvuduko w’amashanyarazi ugufi.
Itsindaicyuma gifunguza imizigoikoreshwa cyane cyane mu guca no gufunga umuvuduko w'amashanyarazi, kandi iyi switch ishobora no gukoreshwa hamwe na fuse ifite voltage nyinshi kugira ngo isimbuze circuit breaker. Kubera ko iyi switch yoroshye gukoresha kandi igiciro kikaba kiri hasi, iyi switch yoroshye ikoreshwa cyane muri sisitemu yo gukwirakwiza 10kV. Guhitamo neza switch zoroshye mu gishushanyo mbonera ni ingenzi cyane kugira ngo amashanyarazi akore neza kandi yizewe.
Imikorere y'iyi switch yo gushyiramo imbaraga ni iyi ikurikira: iyo feri ifunguye, munsi y'igikorwa cy'isoko ryifungura, umugozi mukuru uzenguruka mu buryo bw'isaha. Ku ruhande rumwe, piston izamuka inyuze mu buryo bwa crank-slider kugira ngo ikandagire gaze; ku rundi ruhande, inyuze mu matsinda abiri y'uburyo bwo guhuza bwa bar enye. Sisitemu yo kohereza yakozwe ituma icyuma nyamukuru gifunguka mbere, hanyuma igasunika icyuma kizimya umugozi kugira ngo gifungure aho umugozi uhurira, maze umwuka ufunze uri muri silindiri ugasohora umugozi unyuze mu munwa.
Ihame ry'imikorere y'imashini ikoresha ingufu nyinshi risa n'iry'icyuma gihagarika amashanyarazi. Muri rusange, igikoresho cyoroshye cyo kuzimya umuriro gishyirwaho, ariko imiterere yacyo yoroshye. Ishusho igaragaza imashini ikoresha umwuka ushyushye. Imikorere yayo ni iyi ikurikira: iyo feri ifunguye, munsi y'imashini ifungura, umuyoboro munini uzenguruka mu cyerekezo cy'isaha. Ku ruhande rumwe, piston izamuka inyuze mu buryo bwa crank-slider kugira ngo ikandagire gaze.
Ku rundi ruhande, binyuze muri sisitemu yo kohereza amakuru igizwe n'amaseti abiri y'uburyo bwo guhuza imigozi ine, icyuma nyamukuru kirabanza gufungurwa, hanyuma icyuma cyo kuzimya arc gisunikwa kugira ngo gifungure aho icyuma gihurira, maze umwuka ufunze uri muri silindiri ugasohora arc unyuze mu munwa. Iyo ufunze, unyuze mu munwa mukuru na sisitemu yo kohereza amakuru, icyuma nyamukuru n'icyuma cyo kuzimya arc bizenguruka icyarimwe, kandi aho icyuma gihurira habanza gufungwa; icyuma kinini gikomeza kuzenguruka, ku buryo aho icyuma kinini gifungwa nyuma.
Mu gihe cyo gufunga, isoko rifungura ribika ingufu icyarimwe. Kubera ko icyuma gihindura umuvuduko kidashobora guca umuvuduko mugufi, gikunze gukoreshwa hamwe na fuse ifite ingufu nyinshi. Imikorere yo guca umuvuduko mugufi wa fuse ifite ingufu nyinshi ntishobora kurangiza gusa akazi ko guca umuvuduko mugufi, ahubwo inagabanya cyane ubushyuhe buterwa n'umuvuduko mugufi n'amashanyarazi.
