Great and reliable relays if you are working with Arduinos. I haven't had a single problem in the 6 months of using these.

to power up connect to v+ and v-. then you must apply a trigger to operate the relay. this 12 v relay triggers with 5 v or 12. this is perfect for my application with an Arduino.

The screw terminals are terrible. You have to bend them all up to get a wired in.

12v relay ive had no issues installed 3 so far and they seem to be doing fine. Good thing to have around if you like to tinker.

i tested 2 and they don't work. when the arduino triggers the relay, an indicator LED lights on so everything else is working. NC stays closed and NO stays open, i can only assume the switch itself is stuck.after reading the comments, some people had no problems, some had other problems. i'll test the rest that i already bought, but ordering from this seller is a gamble.

Notice that it’s missing the connectors on the left side where my fingers are. The purchasing picture shows connectors for both sides.
