Tagline

Add smart two-way control to your lights and appliances — no gateway, no rewiring, no complicated setup.

Key Features

• No rewiring required
  Unlike many similar products, Yoswit smart light switches work with both 2-wire and 3-wire traditional wiring. No renovation or extra cabling is needed — just replace the existing wall switch.
• Compatible with traditional two-way switching
  Works together with a conventional two-way switch, giving you more freedom in how fixtures are controlled from multiple locations.
• High compatibility
  Supports common bulb types from incandescent to LED. On single-live wiring, it supports low-wattage LEDs down to 3W.
• Delay and timer functions
  Great for kitchens, staircases, bathrooms and storage rooms. Set a timer so the light stays on briefly after you leave — useful for comfort and energy saving.
• Dual operation modes
  Configurable in the Yoswit App. Use it as a light on/off switch, or as a control switch for an electric door lock / motorized door.
• Switch lock
  Lock the switch safely in ON or OFF state to prevent accidental operation at home, in offices or public areas. Activate or release anytime from the app.
• Customizable LED indicator
  Each switch has an LED indicator. Choose whether it stays always on or only lights when powered — configurable in the Yoswit App.
• Configurable power-restoration state
  After a power outage, the switch can default to ON or OFF based on your setting.
