SWITCH FOR PERIPHERAL I/O DEVICES

摘要

A switch for switching a set of peripheral devices between two computers comprises at least one chip. The at least one chip has a selected signal pin, a group of invariable pins and two groups of variable pins. Each invariable pin corresponds to two variable pins. The group of invariable pins connects to the peripheral devices. Each of the two groups of variable pins connects to one of the two computers. Each invariable pin selectively connects to one of the corresponding two variable pins depending on the states of the selected signal pin to connect the set of peripheral devices to the selected computer.
