PART FINDER FRIDAY – Power jacks!

Pt 101073

PART FINDER FRIDAY – Power jacks! These ubiquitous power jacks are excellent for connecting a standard power supply plug to your project. In general the center contact is positive and the outer is negative. Its common for these jacks to have a switch on the ground, so you can disconnect an internal battery or similar when power is plugged in. We use these in nearly every kit!

    Might be worthwhile to add in some of the r/c and ham stuff, such as Anderson PowerPoles, Dean plugs, and Traxxis connectors, and bullet connectors.
