Masamba amagalimoto amatha kugawidwa m'mitundu itatu molingana ndi momwe amagwirira ntchito: ma elekitiromagineti, solid-state, ndi hybrid. Ma electromagnetic relay amagwiritsa ntchito koyilo yamagetsi kuti apange maginito kuti ayendetse zolumikizana; ali ndi mawonekedwe osavuta koma nthawi yoyankha mwachangu (pafupifupi 10-30ms). Solid-malo otumizirana malaya amagwiritsira ntchito zida za semiconductor (monga ma MOSFET) kuti akwaniritse kusintha kopanda kulumikizana, ndi nthawi zoyankhira kufika pamiyezo ya microsecond, koma pamtengo wokwera. Ma hybrid relays amaphatikiza ubwino wa mitundu yonse iwiri ndipo ndi yoyenera pazochitika zosinthika kwambiri.
Magalimoto owongolera magalimoto ndi zigawo zofunika kwambiri pamakina owongolera zamagetsi pamagalimoto, opangidwa ndi dongosolo lowongolera ndi dongosolo loyendetsedwa. Zidazi zimagwiritsa ntchito mfundo ya electromagnetic induction kuwongolera mafunde akulu okhala ndi mafunde ang'onoang'ono. Monga chimodzi mwazinthu zamagetsi zomwe zimagwiritsidwa ntchito kwambiri pamagalimoto, zimagwiritsidwa ntchito kwambiri pazida zamagalimoto monga nyali zakutsogolo, ma wiper, zoyambira, ndi makina owongolera mpweya, zomwe zimafunikira padziko lonse lapansi kupitilira mayunitsi 1 biliyoni.
Magalimoto oyendetsa magalimoto apanyumba amagawidwa makamaka m'magulu awiri malinga ndi magalimoto omwe amagwiritsidwa ntchito: imodzi ndi ma relay otsatiridwa ndi magalimoto a ku Ulaya, omwe amagwiritsidwa ntchito makamaka pamagalimoto ogwiritsira ntchito luso la Germany ndi French; ina ndi ya ma relay otengera magalimoto aku Japan, omwe amagwiritsidwa ntchito makamaka m'mitundu yaku Japan.
