SUMMARY

The discussion centers on using a momentary switch to control the routing of four USB wires, specifically to switch connections between USB ports. Participants suggest using KVM switches for decoupling USB cables and recommend employing relays for experimentation. A practical approach includes utilizing four automotive relays powered by a 12V source for a more reliable setup. For a finished product, a mechanical four-channel switch with passive peak-suppression on the 5V power channel is advised, although caution is urged regarding USB standards compliance.

PREREQUISITES
  • Understanding of USB standards and wiring
  • Knowledge of relay circuits and operation
  • Familiarity with momentary switches and their applications
  • Basic electronics skills, including working with voltage sources
NEXT STEPS
  • Research KVM switches and their functionality for USB connections
  • Learn about relay configurations and how to implement them in circuits
  • Study the IEEE standards for USB to ensure compliance in designs
  • Explore mechanical switch options for low-voltage applications
USEFUL FOR

Electronics hobbyists, circuit designers, and anyone interested in creating custom USB switching solutions.

Hey guys i have no idea how i would accomplish this, I am pretty sure i would made to make some sort of circuit but what i need it to be able to change where 4 wires go from a momentary switch like these.

an example would be to change which usb port a usb cable is connected to by the push of a button.
 
Engineering news on Phys.org
Are you SPECIFICALLY trying to decouple a USB cable from one port and connect it to another? They make those. They're called KVM switches.

If you're talking about using relays there's a lot you'd have to know. I guess the real first question is:

"Are you actually trying to do this with USB cables?"
 
it is with usb cables yes, its only the one usb device i need though i don't want vga or anything else
 
If you're just experimenting, then you could get four relays driven by a single switch and a 9V battery. It'll be good until the 9V battery dies, and then it will go back to the mechanical default. With Radio Shack prices what they are, you're best bet would be to go 12V and just go to Autozone and buy some cheap automotive relays.

If you're trying to make a finished product, then you could use a mechanical four-channel switch with passive peak-suppression on the 5V power channel of the USB cable. I would hesitate to give you advice on that though since I don't know all the IEEE standards for USB off the top of my head and I bet the ground-switching requirements are pretty rigid for a low-voltage device (especially flash drives).

Sorry, not my area of expertise.
