Screw Terminals with 3.5mm pitch pins.
They have the really cool feature of slide-locking together to form any size you need (4, 6, up to 20 without problems).
Rated up to 125V @ 6A.
Terminal can accept 30 to 20AWG wire. 3.5mm/138mil pin pitch will not fit standard 0.1" perf boards but this is the most common pitch screw terminal.
