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


You might improve the contact life of the ones you have with well
designed contact snubbers, but that might cost a significant fraction
of what better relays cost.

Do all the contacts need to carry more than 1 amp, or just a few of
them?
How much current must the contacts carry (worst case) and what sort of
load is being driven?
