Sometimes usb switches work sometimes they don’t, in general on any pc & i/o device. So WHICH Switch ??
Also which computer with what opsys? Win10 may be touchy, some macs also.
And then there is the issue of usb3 and its problems with AH devices.

There are possibly other switch architectures which may have different problems.

Also they may need external power or not work with some devices that need a lot of power.
Irregular speed and device freezing have been reported with some switches.
One report of frying a keyboard was reported.

Read the reviews and then decide what to do.
While there are many good 5* reviews there are certainly enough with problems to be concerned.
OTOH the device is not that expensive so your best bet may just be to try it.

For sure nobody can guarantee that switch x will work your your unknown computers and be 100% reliable.
