The traditional relay module has complicated wiring and is not friendly to beginners or students. The simple switch module simplifies the wiring method for connecting traditional relays. The input end is equipped with an adapter, which can be compatible with most power sources, battery boxes, DC power supplies, power bank, etc. While simplifying the wiring mode, the functions of relays NC and NO are retained, and the normally open and normally closed modes can be switched by simply adjusting the toggle switch.
DFRobot's latest easy relay module uses a standard Gravity sensor interface and supports a wide voltage input of 3.3V-5.5V, making it easy to connect with main control boards such as Arduino, control board, and so on. Meet your needs in control applications such as robot control, light control, smart home, security, etc.

DOCUMENTS
Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- Gravity
- Gravity is DFRobot’s plug-in connector system for sensors, motors and modules, using standard cables to reduce loose jumper wiring. It matters because Gravity-compatible parts can connect directly to these ports, while non-Gravity parts may need adapters or manual wiring.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- Relay module
- A relay module uses an electrically controlled switch to let a low-power microcontroller control a separate circuit. It matters when switching devices that need different voltages or more current than a microcontroller pin can safely handle.
