Quick connector wire sets make wiring up our arcade-style or metal buttons quicky-quick. Each wire comes as a 'pair' with two 0.187" quick-connects pre-crimped. The wires are terminated together in a JST 2.5mm 2-pin connector. This connector will fit in 0.1" headers, so it's breadboard compatible or you can stick two wires into the end. Of course, you can chop this off if there's no use for it.
If you need a connector for the other side, try this JST XH (matching part from Digi-Key here)
We've found these work with our:
But they are not compatible with the LED contacts Massive and Large Arcade buttons. For those, you'll want the 0.25" Arcade/Button Quick-Connect Wire Pairs. We also have 0.11" Quick-Connects.
We've also noticed that while these are the right size, they may be a little loose on some switches. You can crimp them a little more with a pair of pliers to get a better grip!
