Introduction: Simple USB Switch

This is the most simple USB  switch I could come up with. It doesn't require IC's or any other complex circuitry.
All it requires is:
One 4pdt switch
Two USB female ports
one USB cable
and a case

Step 1: Prepare the Case

this will differ depending on what you use, I used an old power brick.
Just make a hole for your toggle switch and USB ports

Step 2: Wire the Switch

Now the switch needs to be wired.
It doesn't really matter what order the wires are in, as long as they line up on the switch.

Step 3: Test!

Make sure double check the wiring before testing!
It's a good Idea to test this before you put in the case, otherwise you might get all put together, plug in, and it doesn't work

Step 4: Assembly

Now put your USB switch in it's case and your done

Would this work in reverse? like, one female port and two male ports? I want to be able to switch mouse and keyboard between computers without using synergy

Yes, it works in reverse. I needed this way too. Its fully functional. =]

I would also like to know if this could work in reverse. If anyone has any insight into this, that'd be appreciated. I too would like to have a usb switch that can basically act as a switch between a USB hub and two different machines.

This usb switch solve my problem of plunging unplugging USB cables. I use tenda wifi usb router with USB adapter and power bank. With this switch I can keep my usb adaptor and power bank without unplugging and just switching on power failure. This usb switch will not use any energy so that I can save my battery life. USB switcher/hub available in the market have little circuit which consume power and I do not want to loose my power bank battery.

Does this switch turn the two USB ports on and off or does it just switch between them? Would you use this instead of plugging in and unplugging cables? Thanks.

this just switches between the two ports.
right now I don't use it, as I've upgraded my computer and have no shortage of ports, but it is much easier than unplugging the cables, especially if the ports are on the back.

oh, and this particular switch can also turn off both ports
