ABSTRACT:
A display module having a housing constructed to mechanically interlock with the housings of adjacent modules of like construction to form a multiple unit display having either a single display row, or a cluster having first and second display rows. The modules of a display row interlock via male and female dove tail extrusions integrally formed with the module housings, while modules of adjacent first and second display rows interlock via cooperative projections and recesses integrally formed with the module housings and via a common electrical conductor which mechanically and electrically interconnects electrical terminals of adjacent display rows to hold the first and second display rows in assembled relation while simplifying electrical connections to the cluster. A single mounting projection per housing provides support for mounting a row or cluster to a face plate, by selection of predetermined orientations of the modules.
