Smart Switch Manufacturer China

Located in Shenzhen, the global hub of electronics manufacturing, Zowinda combines hardware R&D, firmware development and supply-chain management into one agile partner. Our factory and engineering team focus on smart switches, wireless control modules and IoT sensing devices that meet industrial-grade quality standards.

Whether you need a standard RF wall switch, a battery-free kinetic switch, or a fully customized IoT control module, we provide end-to-end support from schematic design to mass production.

Wireless Switch Module Supplier

Our wireless switch module portfolio covers the most widely used protocols and frequencies:

• RF 433 / 315 MHz — EV1527 learning-code and PT2262 fixed-code receiver modules, ideal for low-cost remote switches, doorbells and controllers.
• Wi-Fi — ESP8266/ESP32-based smart switch modules for direct cloud and voice-assistant integration.
• Zigbee — Low-power mesh-network modules for whole-home smart systems and hotel projects.
• Bluetooth Mesh — For localized, phone-ecosystem control.

All modules are available as bare boards or finished products, with firmware customization and white-label packaging options.

PIR Motion Sensor Switch OEM

We manufacture PIR motion sensor switches for lighting, security and automation applications. Typical specifications include:

We support OEM/ODM for enclosure design, sensitivity tuning, connector types and branding.

EV1527 & PT2262 Decoder Modules

RF remote control is still the most cost-effective way to add wireless switching to appliances. We supply decoder modules for both major encoding schemes:

• EV1527 — Learning-code protocol with ~1 million address combinations, flexible pairing and strong anti-collision performance.
• PT2262 — Fixed-code protocol with hardware address setting, simple and economical for single-function products.

Our decoder modules are compatible with most 433 MHz remotes on the market and can be integrated into smart switches, alarm hosts, motor controllers and industrial remote systems.
