Dolity Normally Closed Relay with Pre Holder and Base Socket 12v 4 High Quality

The media could not be loaded.  This relay is very well made and sturdy. This normaly closed relay solved an issue with my new gauges for my Datsun Z. The high beam LED indicator was opposite of what the lights were doing. This relay solved that issue. Now blue LED is on when high beams are on. Solid clicks from relay seem strong and durable.

Works as it should

I have included a wiring diagram from another listing of a similar product. I have crossed out the connector that is not included with this relay.

Product was used for an escape room puzzle and works as described. Price point is good. In fact I will likely purchase another of these as a back-up. The challenge with this product is the absence of any real wiring diagram. There is no clarity about which wires belong to the switch (control) loop and which belong to the load loop. It would also be helpful if the manufacture provided notes about the electrical requirements (volt range, maximum amps) for both loops.I managed to get this to work through some experimentation; better documentation would certainly have helped. If you expect this product to be intuitive, you may want to look for alternatives.
