I presume USB switch refers to a USB hub with two "output" USB cables, one of which is active at a time. One can toggle the active by pressing a physical button on the switch. Use case: keyboard and mouse are plugged into the switch and you can quickly toggle them between two laptops without messing with the cables.

Yes, this is exactly what it is. Basically a KVM switch without the V. I've been using the display-switch software for months and it's fantastic. Using the inputs on the monitors to do the video switching instead of an external KVM switch means that you don't have to worry about finding a KVM switch that can handle the signal bandwidth required (in my case, three 4K60 HDR DisplayPort monitors, which is not a use case for which most KVM switches are designed).

This is the USB switch I use with it: https://www.iogear.com/product/GUS402/
