the order in which some switches are turned on

Hi all, I have an array of N switches . Initially all are OFF. Somebody turns them ON in some order. It is possible that more switches are turned ON in the same moment. I need a device which shows me the order in which the switches were turned ON. For instance the device should give me: 4,3,1,5,2 (this is the order in which the switches were turned ON). The way in which the output is shown in not important. It must be simple to read (by a human, computer, etc). It is important that the device is able to handle the turned ON (in the same moment) of the multiple switches. thanks, Laura
