Tagline

Control lights and appliances anytime, anywhere — a 1-gang retrofit smart wall switch that works with traditional 2-way / 3-way wiring and requires no rewiring.

Key Features

• No rewiring required
  Unlike many competitors, Yoswit smart light switches work with both 2-wire (no neutral) and 3-wire (with neutral) traditional wiring. Just replace the existing wall switch — no renovation needed.
• Works with traditional 2-way / 3-way switches
  Can be used together with a traditional multi-location switch, giving more freedom for stairways, hallways, large rooms and entrances.
• High compatibility
  Supports common bulb types from incandescent to LED. In live-only (single-fire-wire) wiring, it supports LED loads as low as 3W.
• Delay & timer function
  Great for kitchens, stairways, bathrooms and storerooms. Set lights to turn off after a delay, or schedule them via the Yoswit App.
• Two operation modes
  Configure in the Yoswit App: use as a normal light ON/OFF switch, or as a control switch for electric locks / motorized doors (open/close).
• Switch lock
  Lock the switch ON or OFF to prevent accidental operation at home, in offices or public areas. Enable/disable anytime from the app.
• Customizable LED indicator
  Each switch has an LED indicator. Choose constant-on or power-connected-only behavior in the Yoswit App.
• Configurable power-restored state
  After power recovery, the switch can default to ON or OFF based on user setting.

Installation Warnings

• Disconnect power at the service panel before installation.
• Must be installed by a licensed electrician.
• Strip wires ≈5mm and follow the wiring diagram.
• Ground the device per local regulations; missing ground = unsafe installation / risk of injury.
• Mount to back box, restore power, test 2–3 times, then snap faceplate until all corners “click”.
• Optional LED stabilizer: if 2-wire install causes flicker/no light, use 3-wire (N connected) or add LED stabilizer across any lamp.
