5V DC Operated 1-Channel RF 433 Mhz Wireless Switch With 2 Key 433 Mhz Brown Remote Controller

One Channel RF 433 Mhz Wireless switch with 2 Key 433 Mhz Brown Remote Controller 

This wireless switch works on 433MHz RF frequency and uses ASK modulation for stable wireless signal transmission. It includes a 2-key 433MHz brown remote controller, allowing users to control connected devices remotely. The onboard relay supports up to 10A at 250V AC or 10A at 30V DC, making it suitable for lighting control, home automation, motor control, security systems, and DIY wireless switching applications.

The module circuit itself does not operate directly from 220V AC. A 5V DC supply is required to power the receiver circuit. However, through the relay terminals, users can control 220V AC loads such as lights, fans, and small appliances, or DC loads such as DC motors, pumps, LED strips, and other compatible devices. For DC load control, a separate DC power supply is required. The relay only works as an ON/OFF switch and does not generate AC or DC output voltage.

Its compact design makes it easy to install in DIY projects, automation systems, control panels, or project enclosures. It also supports an external antenna interface, which can help improve the control range up to 10–100 meters, depending on obstacles, environment, and antenna quality.
