Four gang switch

To pick the right four-gang switch, decide between a smart behind-wall module and a conventional four-socket unit. Smart variants use platforms like Tuya/Smart Life and work with voice assistants such as Alexa and Google Home, letting you control four loads from one app. Look for AC 100–240V input, four independent channels, and an invisible design that installs behind your existing wall switch. Brands such as Tuya or Avatto offer these options, with app control and voice compatibility to streamline daily use.

Each channel controls a separate device, lamp, or appliance, so you can run four loads from a single module without rewriting wiring. This enables custom scenes and automation, like turning off the living room lights while leaving a desk lamp on. You can manage all channels via the Tuya/Smart Life app or through voice commands with Alexa or Google Home, giving you flexible control over separate loads from one centralized device.

Tech-forward homeowners wanting full automation and voice control will benefit from a smart behind-wall module, which integrates with apps and ecosystems for remote operation. On the other hand, someone mainly needing on/off control for multiple devices without rewiring may prefer a traditional 4-socket switch with sturdy, high-capacity power handling. The four-socket style commonly supports up to 250V and 16 Amps, making it suitable for a range of household loads.

Electrical installation should be performed by a qualified electrician to ensure safe integration behind your wall switch. After installation, manage on/off and scenes through the compatible app (Tuya/Smart Life) and via voice assistants. Regular checks involve confirming that the device remains properly wired to 100–240V and that app firmware or software is kept up to date for reliable performance.

Choose models built with a flame-retardant shell made from a PC-polycarbonate/ABS plastic blend for safety and durability. Four independent channels provide reliable load control, and compatibility with voice assistants adds convenience. The visible design emphasizes a neat, hidden installation behind existing switches, reducing clutter while maintaining robust electrical performance.

No separate hub is required; these smart four-gang switches connect via the Tuya/Smart Life ecosystem and respond to voice commands from Alexa or Google Home. Setup happens through the app, which handles device discovery and routine creation, allowing you to control four loads from your phone or voice without managing an additional hub.
