No, I think the evil *******s is pretty appropriate! On the other hand, it
may have just been ONE crappy relay. I bought a bunch of parts to put arc
suppressors on all the relays, but never did install them. So, there are
still 11 relays of two different types perking along merrily for the last 3+
years! I was expecting the rest of the relays to start failing, but that
hasn't happened.

It may not have been a bad relay, but may have been that the one relay that went bad was being asked to do something out of spec.

It seems like there ought to be solid state replacements for common mechanical relays. I've never had a failure of an SSR, and you can get them with built in snubbers and zero-cross switching. One would think it would be cheaper to mass produce SSRs vs mechanicals.
