Product information "Screw Terminal Block: 2-Pin, 3.5 mm Pitch, Top Entry (4-Pack)"
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.
The following short video gives a quick overview of how to install these terminal blocks onto our boards:
