The light on my garage door opener has been flakey for sometime now, refusing to go off on it's own and needing to beat on the 'light' button a few times before going off. Finally, it was stuck on for good.Took the controller board out and, sure enough, the "sugar cube relay" was stuck on.It's a common enough part but buying ONE will cost $20 after shipping.Never mind, these relays has the same specs for a fraction of the price.Took one and put it in the garage door opener, and have 7 for spare. lol

Got these for a small project where I needed two relays to activate based on the signal from an Adafruit Trinket MO. Work well.

At first I thought I got lemons because they would not click at if applying 5V DC on low power side according to description. Then I applied 12V DC and they clicked, then I forgot to share the ground when using an ESP32 5V DC sending a 3.2V signal that would trigger both relays at the same time instead of separately, once grounds shared, they worked properly.

Just bought these for a small model train project. I’m now having to return them because neither of the two relays on any of the 4 modules work…. Cheap garbage

I bought these relays for my new CNC machine for wood carving.Nice product. Exactly what I was expecting.Work perfect!

Unit allows using PNP or NPN drivers that cannot drive the current of a relay coil alone. Easily switched from high or low trigger. LEDs help indicate power and state of the inputs. Dry pleased with this simple but well built device. Terminal blocks are not great, but they do function.

These work well. I used them with ESPHome to operate my garage doors.
