摘要

DUAL PURPOSE, WEATHER RESISTANT DATA TERMINAL KEYBOARD ASSEMBLY INCLUDING AUDIO PORTING An improved data terminal utilizing tactile switch assemblies with specialized sound apertures provide reduced panel space requirements and indirect sound paths for miniature electronic apparatus. A maximum number of switches can be accommodated on the instrument panel with no separate speaker/microphone grille required. Non-aligned sound apertures provide maximal weather protection for speaker and microphone mounted behind the switch assembly panel. The switch assembly design seals off the remainder of the unit from weather or dust damage.
