Screw Terminals 5mm Pitch (3-Pin)
Cost: $0.95 each
Description: Screw Terminals with 5mm pitch pins. Comes in 2 or 3 positions and have the really cool feature of slide-locking together to form any size you need (4, 5, up to 20 without problems). Rated up to 300V @ 8A. Terminal can accept 26 to 14AWG wire. 5mm/197mil pin pitch will line up well with standard 0.1" perf boards but the pins are thick enough (1.0mm OD) that you may need to increase the hole diameter on some perf boards.
Note: The 3-pin terminals only connect to other 3-pin terminals. They will not connect to the 2-pin terminals.
