Connected Mains Switch and DIN-Rail Control PCBA
An FCC-photo reference combining a wall-switch power and control assembly with visible antenna placement and a separate connected control-board example featuring an RJ45-form interface.
Project context
How this product is typically engineered
An FCC-photo reference combining a wall-switch power and control assembly with visible antenna placement and a separate connected control-board example featuring an RJ45-form interface.
System architecture
Typical architecture
A representative design conditions mains power, generates a control rail, reads local inputs, and commands a relay or solid-state switch through the product's required insulation strategy; connected variants may add Wi-Fi and wired Ethernet control.
Engineering risks to resolve
Decisions to close before release
- Meet shock-protection, creepage, clearance, surge, and enclosure requirements in a confined wall box.
- Control relay inrush, contact arcing, leakage, and temperature rise across diverse lighting loads.
- Preserve local switching and authenticated state control when network or cloud services fail.
Validation plan
Checks to define before production
- Test resistive, LED, and motor-like load inrush, rapid cycling, contact endurance, and full-load temperature rise.
- Perform applicable dielectric, insulation, miswire, single-fault, surge, EFT, ESD, conducted, and radiated testing.
- Verify metal-box RF performance, local-control fallback, command replay resistance, and interrupted-update recovery.
What to put in the RFQ
Files and records to agree before quoting
Use this list to agree the build inputs and release records for a similar product. The final set depends on the project.
Design baseline
Released schematic or block diagram, interface table, power states, critical constraints, and revision owner.
Manufacturing release
Gerber or ODB++, stack-up, centroid data, assembly drawings, approved DFM dispositions, and panel assumptions.
Material control
Released BOM revision, manufacturer part numbers, AVL or alternate rules, no-substitute lines, MSL handling, and exception approvals.
Validation record
Test method, acceptance criteria, sample or serial identity, measured result fields, and disposition. Example scope: Test resistive, LED, and motor-like load inrush, rapid cycling, contact endurance, and full-load temperature rise.
Production release
First-article status plus the agreed SPI, AOI, X-ray, ICT, FCT, programming, rework, OQA, labeling, and packing records.
During RFQ review, we confirm the required fields, sampling, limits, approvals, and record-retention period. Confidential project information stays within the agreed access rules.
Development and production controls
Typical manufacturing scope
- Mains load switching.
- Wireless and wired control integration.
- Local HMI and power-stage coordination.
Technical image review
Board-level evidence
White-background views are published to make component placement, interfaces and assembly boundaries easier to inspect.
