IIOT-Dual Switch datasheet
-
Hey guys! Currently Im working on smart home/office project. I need to control the light with two way switch method. I need to know where is NO, NC, and COM on PCB. Is there any documentation / datasheet that I can get from internet? If yes please share.
P/s: If you guys have any idea or any other method regarding to this please advice and share.

A1 --> A2 . B1-->B2 all is NO. when you control the G15 and G12 change to digtal high level. they will be close.

@m5stack yes i know how it works, but i need to know where is NC and COM at PCB. So that, i can connect with physical switch and make it two-way switch. That’s why i need a datasheet for relay PCB.

@ahmadhafiz321 actually. this relay module, we did not lead out the NC pin. Therefore, you cannot solder the NC circuit through the PCB.

@m5stack I will use this module too, and need more informations. Can you provide schematic for this circuit? what relay do you use?
