Something that confuses me is why AC and DC relays are not swappable in an application.
For example, I am looking for a 12V (DC coil voltage) relay that its contacts can withstand cold-switching of a 40V/2A DC signal. I found some RT 314 SPDT 12V relays in the lab bin, and I want to use them for this DC application. But nowhere in its datasheet, it has mentioned anything about contact specification in a DC application. Does this mean this relay can not be used in any DC application?
I mean if they can switch 16A,250VAC....why can't they switch 40V/2A DC?
Isn't the relay contact just a conductor?
If not, Do you know a pin compatible relay that can be used in a DC application 40V/2A contact rated?
