Switching Apple 30" Cinema Display between 2014 MacBook and Intel Windows Computer

Using my 30 inch Cinema Display I would like to switch between two computers, being able to use the same keyboard and mouse would be nice but not necessary. My understanding is that I need to get a KVM type switch, but I am totally overwhelmed in trying to figure out exactly which one will work for me. Currently I plug the Dual Link DVI adapter directly into my MacBook's display port, then can unplug from the MacBook and plug directly into my Intel NUC Windows machine's display port. While this works, it would be much more convenient to have a switch. If someone could provide a link to the switch I need, it would be very helpful.
