Just works, simple way to control light bulb, or another power relay for pump, etc.
Inductive or capacitive load can damage the relay. Do not overload it.

Works fantastically, although it was the opposite of what I was expecting at first:
* When [in] is high, 常开(Always Open) and 公共 (Communal) are connected.
* When [in] is low, 常闭 (Always Close) and 公共 (Communal) are connected.

Great price, but 1/3 of mine had a busted LED when I opened the package up.

Seems OK, but I have not used it yet.
