A pack of four 2-pin screw terminal blocks with 5 mm pitch and side-entry wire orientation. Simply tighten or loosen the screws to connect or release wires — no soldering needed for the wire connection itself.
Each block features a ridge on one side and a slot on the other, allowing multiple blocks to slide and lock together to form longer strips as needed. The side-entry design routes wires parallel to the PCB surface.

Jargon buster
Plain-language definitions for the technical terms used above.
- PCB
- A printed circuit board (PCB) is a board, usually rigid, with etched copper tracks that connect electronic components together without loose wiring. Components are mounted on the board and signals route between them through the copper layout.
- Terminal block
- A terminal block is a connector that joins wires together in a neat, removable, or serviceable way, usually clamping each wire under a screw or spring instead of soldering. It makes it easier to connect, change, or service wiring without permanent joints.
