I use this switch internally in my laptop, because the thing without UMTS modem is delivered. So I need a USB Webstick somehow obstruct inside ... which is not easy, because you can somehow change the SIM card is and move the antenna in the screen ...
But this switch is just what you need: The USB ports are from the circuit board - if you ablötet this, the board measures only 3x3cm. I already had USB switches, although they were outwardly small, but the board has since then filled the entire interior and was consequently greater.
