These are like the fancy electronics equivalent of the wire nuts electricians use to bind wires together. They are a lot easier to use as well! Each block connector has a metal block inside and levers that snap open and close to bind stranded/solid-core wire. This Snap-action 2 Way Terminal Block is extremely user friendly, it allows you to wire one circuit to another without any tools. It is suitable for solid wires and multi-stranded wires with a nominal cross section of 0.08 to 4mm.
Each package comes with 3 pieces of 2 Way Terminal Block.
