<![CDATA[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.0_1590659528815_E2923087-07F9-4ED9-9E82-14F001A995B5.jpeg

Can you provide schematic for this circuit? what relay do you use?

Therefore, you cannot solder the NC circuit through the 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.

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