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.

dviem-jungikliais-valdomas-apsvietimas1

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.

kabeliais

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.

Hello, i read your blog occasionally and i own a similar one and i was just curious if you get a lot
of spam feedback? If so how do you reduce
it, any plugin or anything you can advise? I get so much lately it's
driving me insane so any help is very much appreciated.

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?

Hi there! Do you know if they make any plugins to
assist with SEO? I'm trying to get my blog to rank for some targeted keywords but I'm not seeing very good gains.
If you know of any please share. Cheers!
