Cum functioneaza si cum se instaleaza
Functionare
Selectorul rotativ actioneaza circuitul electric doar cat timp este mentinut in pozitiile 1 sau 2. La eliberare, revine automat in pozitia 0, intrerupand alimentarea. Acest mecanism cu came asigura control temporar precis, ideal pentru operatiuni de jogging sau testare echipamente.
Instalare
Necesita decupare circulara de 43mm in panoul electric. Se fixeaza prin strângere pe fata panoului, apoi se conecteaza cablurile la bornele cu surub din spate. Nu necesita scule speciale — o cheie tubulara si o surubelnita sunt suficiente.
Intrebari frecvente
Cat timp ramane activat dupa ce rotesc selectorul?
Circuitul ramane activ doar cat timp mentii selectorul in pozitia 1 sau 2. Cand eliberezi butonul, acesta revine automat la pozitia 0 si intrerupe alimentarea.
Pot folosi acest intrerupator pentru motoare electrice trifazate?
Da, suporta tensiuni pana la 440V AC si curent de 20A termic nominal, fiind compatibil cu majoritatea motoarelor si utilajelor industriale in configuratia AC-15.
Este rezistent la umiditate sau praf in atelier?
Dupa montare corespunzator in panou, ofera protectie IP42 — suficienta pentru medii industriale normale. Pentru expunere directa la apa sau praf intens, necesita carcasa suplimentara.

Inspired to create a chair where the back and arms are moulded from a single piece of plywood
Inspired to create a chair where the back and arms are moulded from a single piece of plywood, Hecht and Colin describe employing a process similar to that a tailor might use to cut a pattern in fabric. This approach resulted in the beautiful structure wherein the moulded back and arms component is supported by a simple A-frame wood dowel construction. One of the benefits of this design is an increase in comfort due to natural movement in the plywood back.

Inspired to create a chair where the back
Made entirely of oak, the Bow Chair is comfortable, visually pleasing and brimming with character. The moulded plywood seat is unusually wide in proportion to its depth and a waterfall edge at the front softens contact with the hamstrings.
