Inkcazo emfutshane:

Iswitshi yokudlulisa ngokuzenzekelayo yochungechunge lwe-dual-power oluzenzekelayo ludibaniso lweswitshi kunye nolawulo lwe-logic, ngaphandle kwesidingo somlawuli owongezelelweyo ukuze afezekise ngokwenene ukuhlanganiswa kwe-electromechanical, kunye nemisebenzi efana nokuchongwa kwe-voltage, i-frequency, i-l yonxibelelwano, umbane, i-mechanical interlock, njl.njl. inokufezekisa ngokuzenzekelayo, i-electric remote, ulawulo lwe-Emergency manual.
