I once made my own VGA switch out of a bajillion-pole/throw/whatever switch I found from an old piece of audio equipment. So pressing one button toggled 8 or 16 or some huge number of independent contacts.

I used it to switch between 1280x1024 outputs from my PC or my Xbox 360. Yes I also bought the official Microsoft Xbox 360 VGA adapter so I could play in HD on my CRT monitor, cause I didn't have an HDTV.

Worked great most of the time, but yeah the switch was a little noisy, and some really freaky stuff happened on the screen if you pressed the switch slowly enough.
