WAGO 50 Pieces 221-412 Connection Terminal 2 Wires with Lever 0,2-4 qmm Small Design, Transparent

I was previously using screw terminal blocks in hobby electronics. These are so much better. Connection is both faster and more reliable. With screw terminals I find a screw will sometimes land to the side of the wire, or only grip the insulation, and it is not always easy to see what has happened. And screws mangle stranded wire, sprinkling broken strands everywhere.With these lever terminals, you strip the wire to 11mm, slide it in, and close the lever, and you KNOW it's connected 100% perfectly, every time. Ferrules are not necessary. The wire is squeezed very securely, but without mangling strands.I'm impressed by how versatile these connectors are. They work equally well for fine or thick wires, stranded or single-core. They're fast enough for quick test connections, but secure enough for permanent installation. They can join two wires together (the 2-wire connectors), or distribute power to several places (the 3- and 5-wire connectors).My only wish is WAGO also made a connector using this mechanism, but with the layout of a standard screw terminal block. I.e., where connections go straight-thru, rather than side-to-side. The wire layout imposed by WAGO's connector isn't the tidiest solution for joining just two wires. But I still prefer the connection mechanism.Each connector has two dedicated multimeter test slots, which are useful, although you can also connect multimeter probes directly as just another wire.The Amazon seller here used a generic bubble envelope with zero information or instructions, but WAGO's YouTube channel has a demo video showing everything (search 'wago 221 series').Overall these connectors are fantastic. They make a solid connection to almost any wire, and I keep finding new uses for them.

Initially sceptical, being a now retired old school electrical engineer. That is until a trial to discover these connectors are invaluable. Not only easy to use and reuse but having never experienced any failure. I believe them superior to the common screwed terminal block. Certainly carry a kit of them now. Easily recommend.

Easy to use, better alternative & more versatile than a choc box,

These are great .

So much easier than the terminal

Good value for money

Wago connectors are great - good bulk buy option

Easy to use. Much safer than connector blocks. No wires on show. Been slowly replacing old blocks i had with these and putting them in the junction boxes.Really happy
