The SwitchBot Relay Switch is a smart device designed to control electrical loads. It supports both AC (100-240V) and DC (12-48V) power supplies. Installation must be performed by a professional in accordance with local electrical regulations. The device requires the SwitchBot app for setup and operation.
Safety Information
- Professional Installation: This product involves high-voltage electricity and must be installed by a professional.
- Environment: Do not use in humid environments, outdoors, or in hot/overheating places. Protect from moisture.
- Installation Location: Install inside appliances or concealed boxes; do not install in areas easily accessible by hand.
- Load Limits: Maximum AC load current is 16 A. Ensure connected appliances do not exceed rated power.
- Safety Precautions: Do not disassemble or modify. If abnormal conditions (smoke, heat, strange odors) occur, switch off the main power supply immediately.
Installation
The device features terminals for O (Load output), I (Load input), SW (Switch input), 12V, L (Live), N (Neutral), and +/GND for DC.



100-240 V AC Power Supply
- Connect the Live wire to the L terminal and the Neutral wire to the N terminal.
- Connect the switch to the SW terminal and the Live wire.
- Connect the load circuit to the I and O terminals.
24-48 V DC Power Supply
- Connect the + wire to the + terminal and the GND wire to the I terminal.
- Connect the switch to the SW terminal and the GND wire.
- Connect the load circuit to the I and O terminals.
12 V DC Power Supply
Follow the 24-48V DC steps, but connect the 12V+ wire to the 12V terminal instead of the + terminal.
Reset to Factory Setting
To restore factory settings, press and hold the device button for 15 seconds. Note that this operation will clear all historical data and settings.
