jungiklisNamuose labai dažnai reikalingas dviem jungikliais valdomas apšvietimas - laiptinėse: apačioje ir viršuje; apšvietimas miegamajame: pagrindinis jungiklis - prie durų, kitas jungiklis - prie lovos; koridoriuose - viename ir kitame gale. Kaip tokiu atveju pravedžiojami kabeliai, skaitykite toliau.




Pirmiausia sienose norimose vietose įtvirtinamos jungiklių montavimo dėžutės ir tarp jų nuvedamas keturių gyslų kabelis.


Jungiklis su vienu kabeliu
(keturių gyslų)

Nuimame laidų izoliaciją (maždaug 1 cm nuo galų) ir pajungiame laidus į jungiklį tokiu būdu:

  • Rrudas (gali būti ir baltas ar raudonas) – jungiklio kontaktas N (C);
  • Juodas (ar mėlynas) – jungiklio kontaktas L1;
  • Pilkas (ar geltonas) – jungiklio kontaktas L2;
  • Geltonas/žalias – jungiklio kontaktas pažymėtas įžeminimo simboliu.




Tuomet nuo arčiausiai prie apšvietimo prietaiso esančio jungiklio nuvedamas trijų gyslų kabelis.


Jungiklio vaizdas su dviem

Pakartojame tą patį (keturių gyslų kabelis pajungiamas į tuos pačius jungiklio kontaktus), tik čia dar pajungiame du papildomus laidus iš trigyslio kabelio:

  • Rudas – jungiklio kontaktas L1;
  • Juodas – jungiklios kontaktas L2;
  • Geltonas/žalias – jungiklio kontaktas pažymėtas įžeminimo simboliu.

Jei nėra specialaus kontakto jungiklyje (o montavimo dėžutė – plastikinė), pažymėto įžeminimo simboliu, visus įžeminimo laidus sujungiame tarpusavyje, panaudodami kontaktinę kaladėlę.



Lieka tik pajungti apšvietimo prietaisą – darbas atliekamas tokiu pat būdu kaip ir pajungiant su vienu jungikliu. Visus kontaktus patikrinus (negali būti jokio laisvumo), galime įjungti automatinį saugiklį ir naudotis.

Paskelbė - visi meistrai vienoje vietoje: santechnikai, elektrikai, staliai, apdailininkai, dažytojai, tinkuotojai, betonuotojai ir kt.

Write more, thats all I have to say. Literally,
it seems as though you relied on the video to make your
point. You definitely know what youre talking about,
why throw away your intelligence on just posting videos to your
site when you could be giving us something enlightening to read?
