Switch arrangement for accessing a computer

In a switch arrangement for providing access to a computer including a plurality of individually actuatable switches, an improvement comprising:

• a first group of switches, first output means responsive to the switches in said first group for continuously providing an access signal, said output means having a plurality of output lines equal in number to the number of switches in said first group and being arranged whereby said access signal is selectively available on one of said output lines, in accordance with the selective actuation of said switches;
• a second group of switches, second output means responsive to the switches in said second group, said second output means having a plurality of output lines individually connectable to particular individual switches of said second group of switches, said second output means including priority assignment means whereby the simultaneous actuation of more than one switch of said second group of switches sequentially connects said output lines to said switches in accordance with the priority assignment by said second output means;
• a third group of switches, third output means responsive to the switches in said third group and having a third plurality of output lines individually connectable to the switches of said third group whereby an access signal is available on a particular one of said third output lines when a particular one of said third switches is actuated.
