I’m looking for an adapter plug that allows a Schuko plug to be connected to a grounded Swiss receptacle. I have found one that is certified to IEC 60884-1 and IEC 60884-2-5. It does not have an SEV mark. Is an SEV mark required for adapter plugs to be used in Switzerland?Thanks,Mike Sherman Graco

I call this “private labeling.”
The EU and presumably the customer want a match between the company name on the
product and company name on the declaration, hence the expectation that they be
the same.

when using EMC-savvy design principles. Extra PCB board spins are cheap in the
