I'm looking for advice/help with designing a USB-A dongle that disconnects power and data lines (I think disconnecting these 3 is the best option?) when a button is pressed and lights up an LED when disconnected.

Key points:

• Button: Momentary NC switch to cut VCC, D+, and D- temporarily. I'd guess that a momentary button that controls 3 separate channels is not a common part. So I guess it'd have to be some switching setup with transistosr/mosfets. Altough I'm kinda lost from this point onwards.
• LED: Turns on when the connection is cut, off when active.
• USB Ports: Male edge on PCB, female soldered to the other end.
• Signal Integrity: D+ and D- lines shouldn’t mess up USB communication when active (not sure if this is an actual concern)

I'd need help choosing parts (button, LED, circuit idea) and tips to make this durable/compact. Any guidance is much appreciated!


I hope that I am in the correct place for this

 

You might start your quest by looking into bus drivers and toggle circuits.

 

You can use a P-channel MOSFET like IRF9540N to disconnect VCC when the button is pressed.

 

What is the goal, or purpose, for such a device??
