## Long description

Sonoff T3US3C is a three-gang Wi‑Fi wall switch in a US standard form factor with a black finish. It replaces a traditional triple rocker switch and provides three independent touch-sensitive channels for controlling lighting fixtures or other hard-wired loads. The switch connects to a home Wi‑Fi network to enable remote on/off control, local manual touch operation, scheduling and automation through supported smart-home apps and compatible voice assistants.
Advantages
The switch offers three separate touch-controlled channels in a single, compact wall plate that fits US mounting boxes. Native Wi‑Fi connectivity removes the need for a separate hub, allowing direct cloud and local control from a smartphone. A minimalist black glass surface provides a modern look and easy-to-clean operation while capacitive touch sensors reduce mechanical wear compared with traditional mechanical switches.
Suitable for
Replacing standard US triple wall switches in residential or office interiors
Controlling multiple lighting zones from a single wall plate
Integrating lights and appliances into schedules and home automation scenes
Voice control via compatible voice assistants and mobile apps

How to use
Turn off power at the breaker before installation. Remove the existing triple switch plate and connect line and load wires to the corresponding terminals for each of the three channels, following local electrical codes. Restore power and configure the Sonoff T3US3C using the manufacturer’s mobile app: add the device to your Wi‑Fi network, assign names to channels, and set up schedules or link with voice assistants if desired. Use the touch-sensitive areas on the panel for local on/off control of each channel.
Usage recommendations
Install the switch in a dry indoor location and ensure a stable 2.4 GHz Wi‑Fi signal at the switch location for reliable remote control. Verify that connected loads (lamps, fans, etc.) are within the switch’s supported electrical ratings and follow local electrical regulations during installation. For advanced automation, create timed scenes or group the switch with other smart devices in the app.
