AC Vs DC ratings...
I have seen a couple of posts concerning AC ratings on switches Vs using DC
on them and the switches not lasting as long. Can someone tell me the
difference between the effect a DC current has on a switch and an
equivalent RMS AC current. I guess what I am asking is : what effect does DC
have over AC in switch contact life?
