Addon - Spring loaded audio wire connector

I missed a fast way to connect a DC motor or a LED to the power supply without the need of 4mm banana connectors. Some of the other DPS5005 power supply projecs use sping loaded audio wire push connectors. I think, thats a very good idea and so i added one to my portable power supply.

You can probably make the contacts using this: 1/4" quick connect spade male

For your Accu-Pack adapter contacts. They are the same type of connector as the spades on your on/off switch (that you soldered). Those are actually for quick connect.
