These are handy connectors for connecting wires to a printed circuit board. The spacing between the pins is .2 inches. We use these on our MOSFET plugs, Relay plugs and for many semi-permanent lash-ups. They clip together so you can make continuous terminal blocks with any number of even terminals.
They also work great on wired or wireless breadboards. Although some holes may require a little enlarging to mount, the pin centers line up perfectly with wired and wireless breadboard holes.
