The ground contactor is not connecting with the barrel on the unit I purchased. I hope it’s just a fluke, so I’m buying another one. I’ve tried pushing the tab back and forth and up and down with no luck.
It also would be nicer if these were regular through-hole pins instead of the tabs. The layout for this part on sparkfun’s eagle library just has round holes that these tabs don’t fit through.
