Perfect for presentations, these switch boxes will easily house up to four 15-pin VGA/SVGA and 6-pin mini din connections used with PS/2 bus-style keyboards. Fear of system lock-up is unnecessary due to the fact that no power is being drawn from the keyboard ports, and each box has a durable, metal casing which helps prevent any unwanted EMI/RFI interference from distorting the signals.
