Iyo agasanduku k'ishami ry'insinga ifite ingufu nyinshi gashyushye, kagenzurwa hakurikijwe uburyo n'uburyo runaka kugira ngo katazagira ingaruka ku rugero runaka mu buryo nyabwo, kandi kagire ingaruka ku mikorere n'agaciro mu mikoreshereze nyayo; icya mbere, gukora igenzura ry'ubushyuhe, hakurikijwe ubushyuhe bw'ubushyuhe n'umuvuduko w'iterambere ugena niba ari ngombwa gushyira ku mucungamutungo kugira ngo uhindure uburyo bwo gukora cyangwa kugabanya umutwaro, kandi uhindure uburyo bwo gukora; icya kabiri ni ugusana switch yo kwitandukanya, muri rusange gusimbuza clamp ya static contact spring no gutwika intoki za contact, gukuraho urwego rwa oxide rw'ingufu zihindagurika n'izidahindagurika, no gusukura ingufu zihindagurika n'izidahindagurika. Shyira kole iyobora hanyuma ukaze bolts. Uburyo bwimbitse ni ugusimbuza ingufu zihindagurika.
Agasanduku k'ishami ry'insinga zifite ingufu nyinshi kamaze igihe kinini gakora, ibikoresho bikunda gusaza, imiterere y'isoko yo gukanda urutoki idahindagurika irangirika, cyangwa urutoki rudahindagurika rukora ku ruhande rumwe, isoko yo gukanda rudahindagurika irarekuye kandi irangiritse, kandi imbaraga zo gukanda ntizihagije kugira ngo igice cy'urutoki rukora kigende. Ingano ntizikora ku ruhande, kandi ubushyuhe bukunze kubaho iyo umutwaro mwinshi w'impeshyi ari munini; bityo, kubungabunga buri gihe agasanduku k'ishami ry'insinga zifite ingufu nyinshi ni bwo buryo bw'ingenzi bwo kugabanya ingaruka z'ibicuruzwa.
