Nice,
Could you give some more details ?
What is the swiches for?
Does they allow to switch of the USB/TTL device to save power when not in use ?
It would be a nice feature according to me.

I use switch to auto upgrade firmware instead of button, not for switch of the USB/TTL signal. USB device in poweroff mode when USB line is not plugins.

I can't do a complete verification now for some reason, but I do some tests and believe it can work normally. I will share files in github next week.
