These terminal blocks have terminals that hold and release wires through the simple adjustment of a screw, allowing you to easily make temporary connections to a PCB. The 2-pin and 3-pin units each feature a ridge on one side and a slot on the other, which lets them slide and lock together to form arbitrarily long strips with a pitch of 3.5 mm or 5 mm. Each terminal block is available in two orientations: side-entry and top-entry.
This product is a four-pack of 5mm-pitch, three-pin, top-entry terminal blocks. The more general dimension diagram for an XX-pin version of this screw terminal block is shown below.
