MakerBot Print is our newest print-prepration software, which supports native CAD files and STL assemblies,
allows you to interact with all your printers via the Cloud, and many other exciting new features.
it can be used to redirect the power source. the power (battery) arrives at the center pin and can be redirected to a consumer on the left pin or on the right pin. in my case the pi is connected to the right pin and the left pin is free.
so if I slide the switch to the right, the center and the right pin are connected -> pi boots.
If I slide the switch to the left, the center and the left pin are connected -> nothing happens.
Left = off.
Right = on.
Of course you can use any other switch. With that less current (max. 1,9A) it doesn't matter.
