The switch provides power to the disk in the caddy. It has nothing to with any disks you have inside the machine. So you will have to press the switch before starting the machine if you want to boot into the disk in the caddy.
If you are already booted into a different disk, then you could press the switch and the disk in the caddy appears in explorer just like any other, you can copy to and from it, etc. Then it can be ejected with the safely remove icon or whatever it is called nowadays and then turn the swich off.
