Ma relay ndi ma switch ofunikira amagetsi opangidwa kuti aziwongolera mabwalo amphamvu kwambiri pogwiritsa ntchito ma siginecha amphamvu otsika. Amapereka kudzipatula kodalirika pakati pa zowongolera ndi zonyamula katundu, kuwonetsetsa kuti zikuyenda bwino komanso moyenera m'mafakitale osiyanasiyana, kuphatikiza magalimoto, makina opanga mafakitale, zida zapakhomo, ndi matelefoni.

Zofunika Kwambiri:

• Kulemera Kwambiri - Kutha kusintha ma voltages apamwamba ndi mafunde molondola.
• Nthawi Yoyankha Mwachangu - Imawonetsetsa kuwongolera mwachangu komanso molondola.
• Moyo Wautumiki Wautali - Kumanga kokhazikika ndi kupirira kwamakina komanso magetsi.
• Kugwirizana Kwakukulu - Kupezeka m'makonzedwe osiyanasiyana (SPDT, DPDT, etc.) kuti agwirizane ndi ntchito zosiyanasiyana.
• Kugwiritsa Ntchito Mphamvu Zochepa - Kugwiritsa ntchito mphamvu zamagetsi ndi zofunikira zochepa zowongolera.
• Kudziteteza Kudzipatula - Kumateteza kusokoneza pakati pa zowongolera ndi zonyamula katundu kuti mutetezeke.

Mapulogalamu:

• Industrial Control Systems - Kuwongolera magalimoto, ma PLC, ndi zida zamagetsi.
• Zamagetsi Zamagetsi - Kugawa mphamvu, kuyatsa ndi kasamalidwe ka batri.
• Zida Zam'nyumba - Makina a HVAC, mafiriji, ndi makina ochapira.
• Telecommunications & Power Supplies - Kusintha kwa ma Signal ndi chitetezo chozungulira.
