For non critical home and auto projects these are a good option. Totally no frills (well they DO have an LED), with no kickback suppression built in and the LED is polarity sensitive. Wire Positive to 8 (Right side) and negative to 7 (Left Side). Use your own Kickback Suppression diodes (I like 1n4007 or Mallory PTC 205 for this application) Some engineers use a capacitor but I'm old school and like the diode. Pros: #1 - Super affordable, at least for now, these relays come branded with several gibberish names, they are all the same so far. Cheap no name relays (that work well short term, maybe even long term) #2 - Good features, LEDs are easily visible #3 - Work as well as Idec, Allen-Bradley, etc at a tiny fraction of the price. #4 - Come with Decent sockets, a 3 relay wide piece of Aluminum DIN rail, even screws to fasten your DIN Rail with! Cons: #1 No top mechanical indicator flag, there's a window for one, but no flag, they are 2 very tiny windows (non-frosted areas) on each side right at the contacts, but those are almost impossible to see once in a panel. #2 - No internal suppression on DC models - you get all sorts of stuff included, but sadly, no suppression diode. #3 - Polarity sensitive LED, don't follow convention here, check. (ask me how I know) #4 - Cheap no name relays - NOT to be used for critical applications. Don't use this as a control for a heater or something that can burn down a building or otherwise risk life or property. They work OK for now, I've had some in service for a month or more with no issues, but long term, who knows? #5 May not be available later, Be kind to the next tech (you?) and leave a couple spares in the panelbox. All told I managed to justify 5 stars, the negatives, none of which is horrible, are made less of an issue by the price. As time grows I gain confidence in these, but I won't be controlling any hazardous devices with them, and don't advise you to either. That being said, upon close examination, they seem to be built the same as the brand name ones, with nothing visually alarming. I do wonder what the contacts are made of (but they appear "standard"), and if the coil is actually copper (it's soldered in place and seems to weigh enough that I'd expect it is indeed real copper, not "CCA" (Copper Clad Aluminum" - the bane of electrons and their keepers worldwide)) All up, these are a great product for the hobbyist (Or financially strapped small company) to use in intrinsically safe equipment controls. I owned and operated a small Industrial controls business before I retired, and have been using relays since the '70's - just so you know I'm not new to the product. PS an Idec, PB or AB relay like this would run $20 to $50+ depending on where and how many you buy. (Please don't judge my panel, it's a work in progress (but operating) and isn't dressed out yet)

Works as advertised. Easy setup with the DIN rails. The attached image shows the relay pinout. Hard to read on the relay itself.

They work. They are cheap. You get what you pay for, not more and sometimes less.
