A display apparatus for use with a system for routing at least one type of signal between a desired source device (17a-17p) and a desired destination device (18a-18p). The display apparatus includes a panel having a plurality of buttons mounted thereon. Each of the buttons respectively represents the type(s) of signal(s), the available source device(s) and the available destination device(s). The type(s) of signal(s) may be selected by a terminal device (11) included in the system and the source and destination devices may be selected by activating the respective button. Each of the buttons contains a plurality of luminous elements each adapted to emit light of a respective colour. As a result, the type(s) of signal(s), the source device(s) and the destination device(s) represented by the buttons and selected ones thereof may be readily identified. <IMAGE>
