3 Pin PCB Terminal Block 5mm Pitch 10A Rating YX126Terminal blocks (also known as screw terminals) are electrical connectors that allow you to connect wires in the same circuit without cutting or splicing them. Screw with 3 pins. The Terminal Block is a multifunctional and small terminal block. It's used to connect wires to the circuit board. The terminal block's small size allows it to connect two conductors on a PCB where space is at a premium. The wires are held in place by screws on this terminal
