These terminal blocks have spring terminals that automatically grip inserted wires and release when their levers are pressed with a fingernail or small object, enabling easy, temporary connections to a PCB.
These terminal blocks can be combined to make longer ones, or segments can be removed to make them shorter. Each block has two pins per terminal, and they are intended for use with PCBs that have the appropriate footprints; they do not work well with solderless breadboards because the legs are too short.
