Smart switches combine mains voltage and radio modules. Buyers should separate marketing badges on a website from documents tied to a SKU and factory lot. Trading platforms can source certs — they should not invent numbers on a brochure page.
Common marks (high level)
- CE — EU-facing electrical/RF narrative; ask for LVD/EMC report scope matching the model.
- RoHS — material restrictions; often paired with CE retail channels.
- FCC — US RF devices; module grant vs host product questions matter for Wi‑Fi switches.
- UL — where the product category and retailer require it (especially sockets / higher scrutiny lines).
- UKCA / SASO / others — project or country driven; state destination early.
Questions that belong in every RFQ
- Destination country and channel (retail / project / online brand)
- Exact model / family after sample approval
- Whether RF module certificate is acceptable alone
- Language of reports and whether third-party retest is needed
- Lead time to prepare the document pack after PO
