Power switch for Beaglebone?

Is there a simple passive switch I can put between the Beaglebone
White and its power supply so I can switch it on and off without
unplugging it?

I'm not sure. I'm just looking for a small component I can plug
between the Beaglebone and power cable without any soldering.
