I have got a very beginner question. I am building an irrigation system and so I need to use a 12V solenoid valve. My question is as follows: Given the following valve and in particular the contacts (at the bottom): enter image description here I have connected it to my relay (and ground) with some alligator clip to prototype (it works), but how can I connect it in a more serious (production-ready) way?

Thanks,

    just a note: the picture shows the valve upside down .... always orient with electrics at the highest point, to keep water out as much as possible – jsotola Oct 11 '20 at 19:22

    yes. I found the picture on the internet, but your comment makes a LOT of sense. – Edge7 Oct 11 '20 at 19:45

The connectors you see in the image are known as spade connectors, also push-on spade connectors, typically in insulated and non-insulated forms.

The above Amazon link is but one of many sources. Harbor Freight has available for purchase a few assortments of terminal connectors. For small quantities, at proportional higher prices, one can certainly find these spade connectors at local auto parts stores. I have three stores within two miles and all of them carry various sizes of the connector, both male and female connections.

You'll probably find that you can only buy matched sets, if you need only the two. Maybe a box of six, three of each, at an auto parts store. Check the wire gauge you plan to use and match that with the legend on the box.
