Touch light switch Sonoff T3 EU TX WiFi RF 433 2-channel — wall-mounted smart switch, EU touch panel

Sonoff T3 EU TX is a wall-mounted 2-channel touch light switch designed for smart home lighting control. The device combines a capacitive glass touch panel with Wi‑Fi connectivity and RF 433 MHz compatibility, allowing local touch control of two independent circuits and remote control through a mobile app or RF remote. The slim EU-format panel fits standard wall boxes and works with existing wiring to replace a traditional double switch while adding smart features.

Advantages

The Sonoff T3 EU TX provides dual-circuit control from a single wall plate, enabling separate management of two lighting circuits. Capacitive touch buttons offer smooth, silent operation and a modern aesthetic. Built-in Wi‑Fi allows remote switching and scheduling via the manufacturer's app, while RF 433 MHz support enables pairing with compatible remote controls for offline use. The unit is designed for straightforward installation in standard EU back boxes and supports both local manual control and cloud-based automation.

Suitable for

• Controlling two independent lighting circuits in living rooms, bedrooms, kitchens, or hallways
• Integrating wall-mounted switches into a Wi‑Fi smart home system for remote control and scheduling
• Replacing a standard double rocker switch with a modern touch panel
• Using with RF 433 MHz remotes where Wi‑Fi is unavailable or as a secondary control option

Key specifications

• Number of channels: 2 independent circuits
• Control methods: capacitive touch panel, Wi‑Fi remote control, RF 433 MHz remote compatibility
• Mounting type: wall-mounted, EU standard back box compatible
• Panel material: glass capacitive surface
• Power supply and switching: designed to work with mains voltage household wiring (follow local electrical standards)

How to use

Install the Sonoff T3 EU TX in an EU-standard wall back box, connecting live and load wires for each channel according to the included wiring diagram and local electrical codes. After powering the device, use the capacitive touch areas on the glass panel to switch each circuit locally. To enable remote control and automation, follow app pairing instructions to connect the switch to a home Wi‑Fi network and register it in the mobile application. For offline remote operation, pair a compatible RF 433 MHz remote with the switch following the manufacturer’s pairing procedure.

Recommendations

Ensure power is turned off at the circuit breaker before installation and follow local electrical regulations or hire a qualified electrician. Use the mobile app to set schedules, scenes, or timers for energy-efficient operation. If combining with other smart devices, verify compatibility and network capacity to maintain reliable remote control.
