Come see yet another freak of nature, a combination 2.1mm Barrel Jack plus Slide Switch in one! And like all freakishly weird creatures, it is strong as an ox! Rated at 3A (@16VDC) this mini behemoth can take on all you can throw at it (well there are limits, but we're just sayin' it's awesome)!
Micro Deans plugs are usually used in RC vehicle applications but can also be used for all kinds of other high current, small form factor projects. They even have a polarity protection feature built into the design, bonus!
