Default relay rating question

How much current are you trying to switch? If you have
100, and only need 38, put two in parallel for each
circuit; that'll give you 2A.

But frankly, I wouldn't depend on it being good for
much more than the rating. I've seen relays where
the contacts were rated for one current at 240VAC,
and _less_ current at 28VDC, but that's one of the
differences between switching AC and DC.

Good Luck!

Thanks, the only reason i'm not just going out an buying the higer rated
relays is that i already have 100 of the 1A 120vac around the house and need
to use about 28 for the project i'm working on so its an expensive
proposition. Unless some one knows of a cheep source


Simple, Try one, see how hot it gets.
Relays can dissappate heat through the pins, so if you are making
your own pcb for them , try to have a lot of copper around the contact
pins.
