Sorry, maybe it's a little bit hard for me in English to express how i mean it.
If the 1$ relays are not cheap (in the meaning of quality) then it does not
change the thing that i can use them for almost anything without to think
to much about it.
What is a cheap relay where i need to be scared that it runs with a lamp
but get killed if i use it on a valve - one for 2 cents?
