Im off to the states and wondered if buying a saitek switch panel as well as all the other panels saitek sell, would work on my pc when I got back home to the u.k.?.

I don't see any reason why not (- you'll save on the VAT too!) Have a nice trip :)

It will work fine. I bought my gear in North America and it works fine in New Zealand. USA is 110 volt and New Zealand is 240 volt.....The switch on the back of the computer in the power pack has a switch for 110 or 240....The power pack converts the voltage from then on for the rest of the computer components. Saitek gear is USB so it will work anywhere in the world as USB power is universal.
