Iyi switch yo gushyiramo umuriro ni igikoresho gihuza icyuma gihagarika umuriro n'imashini yo kwimura umuriro. Ifite ibikoresho byoroshye byo kuzimya umuriro, bishobora kuziba umuriro w'inyongera n'umuvuduko w'amashanyarazi urenze urugero, ariko ntishobora kuziba umuriro w'amashanyarazi urenze urugero. Iyi switch yo gushyiramo umuriro ishobora gufungura no kuzimya umuriro w'amashanyarazi, umuvuduko w'amashanyarazi ushyushya, umuvuduko w'amashanyarazi ushyushya umuriro n'umuvuduko w'amashanyarazi ukoresheje capacitor mu gihe cy'imikorere isanzwe.
1) Imashini ikoresha ingufu nyinshi zo mu bwoko bwa vacuum: ikoreshwa ry'icyuma gikoresha vacuum mu kuzimya umugozi, amashanyarazi amara igihe kirekire, igiciro kiri hejuru, kandi ikwiriye ibicuruzwa bya kV 220 no munsi yayo.
2) Imashini ikoresha ingufu nyinshi ikoresheje amavuta: Ikoresha ingufu z'icyuma ubwacyo kugira ngo ibore kandi ihindure amavuta akikije icyuma, ikonje kandi ihagarike icyuma.
3) Imashini ikoresha ingufu nyinshi zo mu bwoko bwa hexafluoride yo mu bwoko bwa sulfur: ikoresha gaze ya hexafluoride yo mu bwoko bwa sulfur mu kuzimya umuyoboro w'amazi, umuyoboro wayo wo gucika ni munini, kandi imikorere y'umuyoboro wa capacitor wo gucika ni myiza, ariko imiterere yayo ni mibi cyane, kandi ikwiriye ibicuruzwa bya kV 35 no hejuru yayo.
4) Imashini ikoresha ingufu nyinshi z'amashanyarazi: Ikoresha umwuka ufunze wa piston mu gihe cyo gucika kugira ngo ikureho umurambararo, kandi imiterere yayo ni yoroshye, kandi ikwiriye ibicuruzwa bya kV 35 no munsi yayo.
5) Ingufu zitanga umwuka ukomeye zikoresha ingufu nyinshi: Koresha ingufu zo kumena arc ubwayo kugira ngo ibikoresho bitanga umwuka biri mu cyumba cy’arc bitange umwuka wo gusohora arc. Imiterere yayo iroroshye, kandi ikwiriye ibicuruzwa bya kV 35 no munsi yayo.
6) Imashini ikoresha ingufu nyinshi zo mu bwoko bwa "compressed air type": gukoresha umwuka urimo imbaraga nyinshi mu gusohora arc bishobora guhagarika umuvuduko munini w'amashanyarazi, kandi imiterere yawo ni mibi cyane, ikwiriye ibikoresho bya kV 60 no hejuru yayo.
