On sale is this USB 3.0 Switch that acts similar to a KVM switch in that you can share 4 USB 3.0 peripherals such as a printer, mouse, keyboard, USB flash drive etc. between two computers and switch between them with a press of a button. Unlike other brands this one comes with an external button on a long USB-C cable to make it easier to switch between computers.
Edit: Discount may only show for AliExpress members above Silver (e.g. Gold, Platinum and Diamond).
As an example I currently have one connected to my Windows PC and the other to my Mac so I can use the same keyboard and mouse between both computers. I simply press the button and the keyboard/mouse works with the Windows PC and press it again to switch control to the Mac.
If you're wanting to run something that requires more power (e.g. external HDD with power adaptor) there's a micro USB port on the back that you can hook up to a charger.
