Looking for Hardware with a physical on / off switch, usb and that could be used via HAS too

Hi all,

I am looking for Hardware with a physical on / off switch, usb and that could be used via HAS too…

Maybe it doesn’t exist yet…

It would look something like: https://www.amazon.co.uk/USB-OFF-SWITCH-3-0-HmbG/dp/B00RC1NFEI
Preferably a little bit thinner.

Beside this specific hardware, how would one know which hardware is compatible with HAS?
