The main feature of the Sonoff Dual switch is the conversion of your simple devices into smart ones. Connect the power supply of your 4 devices to the switch, and control them simultaneously or independently, from wherever you are, via your smartphone, tablet, or your favorite digital assistant.

It features three operating modes: self-locking, where you can turn all your devices on and off together, interlock, which allows you to turn on one device and turn off the others, and inching, where the connected switch operates as a pulse switch. Additionally, it has a built-in RF receiver, allowing it to control RF devices that have a remote control.
