Review on 📡 Optocoupler Support Trigger by HiLetgo Channel by Scott King

UPDATE: These are identical to Jungner's and after testing 6 at low voltage only 7 worked. And I don't have high hopes for durability. just trash. I'll be back. I built my project and tested the low voltage load and everything worked for my test case. As soon as I connect the correct AC load across the relay it becomes unreliable. If I disconnect the AC load and try the low voltage test again, it still doesn't work. It opens normally, but then does not return to the closed state without lightly tapping the relay. Needless to say, this makes the application pretty much useless. In addition, they are identical in construction to the much cheaper Youngneer relays, which are significantly cheaper. You have the same problem. The description for the relays says they can handle 240v at 20 amps, which is far more than my load of around 1.5 amps at 110v. So what's there?
