Any small electronics Gurus here?

Need help on what should be a simple thing if I knew what I was looking for.

I'd like ? in the image below to cut the circuit to the switch when the 3.3 to 5 volts power is on.
The pass through voltage for the switch would not exceeded 5 volts and is only used to ground the RX circuit.
The switch is a SPST Normally Open Momentary.

What this does (Or should do) is disable the switch circuit if the USB device is plugged in as that is where the 3.3 to 5 volts is drawn from.

And it needs to fit in here along with the switch.
