What does the Switch pins do on the SAMD21 Pro RF?

I looked at the datasheets and they just say Switch. Where can I find information about what these pins do and how to use them?

Looking at the schematic (found under the documents tab at https://cdn.sparkfun.com/assets/f/f/8/e … ematic.pdf ), the switch pads are in parallel with the power switch SW1. They are used if you want to use a panel-mount or external switch to power up the board. Leave SW1 off if you are using the external switch.
