Pezani malo atatu Sf. Katundu wa switch switch, kulekanitsa mwanzeru mizere yolowera kumanzere ndi kumanja yolowera ndi yotuluka, kapangidwe kakang'ono kamangidwe, kachitidwe kolimba kwambiri kachingwe, mpaka mizere 8 yolowera ndi yotuluka. Bokosi lanthambili silimangosunga zabwino za bokosi logawa ulusi, komanso lili ndi zovuta zina zagawo lalikulu la mphete. Ndi zida zabwino zosinthira maukonde akutawuni. Kukula kwakung'ono, kopanda kukonza, chuma chabwino chaukadaulo, kudalirika kwakukulu, kukhazikitsa kosavuta komanso kugwiritsa ntchito kosavuta.

Ndi SF. Makhalidwe a bokosi la nthambi yamagetsi ya chosinthira katundu ndi: pali zipinda zitatu mu chipinda, chimodzi chomwe chimasindikizidwa. Chipinda chosindikizidwacho chimadzazidwa ndi mpweya wa sulfure wa hexafluoride wopanikizidwa pang'ono, ndipo pali magulu angapo osinthira katundu mmenemo. Njira yogwiritsira ntchito yosinthira katunduyo ili mu chipinda choyendetsa galimoto. Pali milu yamagetsi yamagetsi ndi ma terminals amagetsi m'chipinda cha waya wamagetsi, ndipo ma terminals amagetsi amalumikizidwa ndi switch switch. Kusintha kwa katundu mu chipinda chosindikizira chosinthira ndi chosinthira champhamvu komanso cholumikizira cholumikizira. Shaft yozungulira ya chosinthira chilichonse chimakhala ndi zigawo zitatu pa ndege yofananira yozungulira mozungulira. Zingwe zomwe zili mu chipinda cha chingwe zili mu gulu la magawo atatu, ndipo ma terminals atatu amagetsi mu gulu lirilonse amagawidwa mofanana ndi diagonally pansi. Ma terminal a njoka yamagetsi iliyonse amalumikizidwa molunjika ku mawaya owonjezera amagetsi, ndipo mizere itatu ya mulu wowonjezera wamagetsi imafanana. Chipinda chosindikizidwa chimakhala ndi chitoliro chokakamiza.
