I don't understand why they need to be switched. Can someone explain?

In theory it's just to save power by shutting something off instead of just unplugging it.

It's power and convenience. On a different switched hub I have external HDDs, that I want to stay offline for better security and less wear.

Instead of fiddling with cables I can just hit a switch and have them spun up to use in ~10 seconds. When the USB3 connection is severed by hitting the switch again, they automatically spin down and don't really need their AC/DC adapters unplugged because they draw practically nothing when the HDD isn't running.

The USB 3 version is available here:
https://www.amazon.com/Sabrent-4-Port-Individual-Switches-HB-UM43/dp/B00JX1ZS5O
for $7. Personally, I have a powered hub, because the one amp of available power for four devices seems inadequate.
