Cut power with the pull of a plug when you need to swap out equipment or adjust your circuit. You can wire the plug away from the terminal block, then pop it into the socket you've already installed. Pins on the bottom of these blocks are spaced to match the layout of circuit boards. Solder them onto your board for a secure hold. You'll need one plug and one socket for a complete terminal block.

The screw-clamp terminals flatten your wire so it stays put when vibrated or pulled. For an even stronger and more conductive connection, crimp a terminal or wire ferrule onto the end of the wire.
