I've found that the mechanical switches can be deadly to the motherboard. The
main thing you need is a clean break between systems - if you end up sliding
across the contacts from system 1 to system 2, Bad Things Happen. One solution
is to leave a "blank" between your two main systems:
A: Windows Box
B: No Connection
C: Linux Box
Of course, that means only two systems on the four port switch. The other is
to switch to a "blank" position, then back to a live one. This may work with
up to three systems on a four port switch.
Frankly though, for more than two systems or for any serious work, it's worth
the money for an electronic switch. Get one that will emulate the mouse when
it's not online so reboots are easier if you can. Shop lots - you can find
decent ones from about $100 to well over $1,000.
