Wholesale Wifi Light Switch Uk Supplier & Factory

Corunsmart switches are engineered specifically for the British electrical standard BS EN 60669 and BS 1363. Unlike US rectangular panels or standard 86mm Chinese switches, our UK switches feature precisely calculated 86x86mm dimensions with standard 60.3mm mounting screw centers. Furthermore, the internal mechanical housing has been ultra-slimmed to less than 24mm depth, allowing comfortable flush-fitting into shallow 25mm or 35mm British steel patress boxes without requiring wall gouging or spacer brackets. We also provide both standard Live+Neutral and specialized Single-Live (No Neutral) configurations with built-in snubber circuits to prevent LED bulb ghosting.

In typical UK two-wire installations without a neutral line, smart switches must draw micro-current through the lighting filament while in the "off" state to keep the Wi-Fi or Zigbee chip powered. This low leakage current often charges the capacitors inside low-wattage LED driver circuits, resulting in periodic strobing or buzzing. Corunsmart incorporates a proprietary ultra-low-power micro-switch circuit requiring less than 0.15W of quiescent standby power. For ultra-sensitive LED bulbs below 5W, we provide an optional matched ceramic anti-flicker bypass module (capacitor snubber) connected across the primary lamp load (L1 to N) to ensure zero ghost light emission.

Our products and production processes maintain verifiable full-tier compliance. The Shenzhen production facility is ISO 9001:2015 and BSCI certified. For finished goods exported to the UK and European Union, our Wi-Fi light switches and smart relays carry valid UKCA (covering Radio Equipment Regulations 2017) and CE-RED certificates issued by accredited third-party test houses. Additionally, materials are verified under RoHS 2.0 (2011/65/EU) and REACH, while plastics use UL94-V0 flame-retardant Bayer polycarbonate that conforms to glow-wire tests up to 850°C.

Yes. Corunsmart heavily utilizes Espressif ESP32, ESP32-C2, and ESP32-C3 system-on-chip (SoC) architectures alongside Tuya Wi-Fi modules. For smart home brands, industrial integrators, and security-conscious commercial clients who operate their own local servers or platforms, we offer factory flashing of open-source Tasmota, ESPHome, or custom compiled proprietary C/C++ firmware. Hardware test points (TX/RX/GND/GPIO0) can also remain accessible on designated PCB variants to support downstream field modifications.

Standard evaluation samples are typically dispatched within 3 to 5 working days. For bulk OEM orders featuring customized laser-printed logos and private label packaging, our minimum order quantity (MOQ) begins at 500 to 1,000 units per SKU, with production lead times running between 20 and 30 calendar days depending on seasonal component allocations. For complex ODM developments requiring new physical injection tooling for front panels, mold development takes approximately 35 days from CAD signoff to initial plastic shot validation.

Our quality control workflow is strictly segmented into four distinct stages: IQC (Incoming Quality Control) for passive components and ICs; IPQC (In-Process Quality Control) utilizing automated optical inspection (AOI) on all SMT lines; 100% functional EOL (End-of-Line) electrical safety isolation testing; and OQC (Out-going Quality Control) statistical batch inspection. Every single smart switch module undergoes automated high-voltage surge simulation and a 4-hour active load burn-in cycle in temperature-controlled chambers before entering final packaging.
