Yes, you can talk through the switch. There are dozens of ways to communicate through peer to peer chat platforms. Which is why I find it so damn laughable that Anons keep trying to "decode" celeb video's for their "Comms". If James Comey is trying to tell Hillary how many babies Patten Oswalt and David Spade need to eat this week there are much better, safer ways to do it than world wide video broadcast.
