Dovetail base assembly for keyswitches.

摘要

Keyboard switch modules have connectors for attaching one module to another and to form a modular structural base assembly for constructing a custom key switch array which includes a foundation structural base module and a grouped keyswitch station arranged similarly to a typewriter key matrix. Accessory base modules of various keyswitch groupings can be attached to the foundation module to permit addition of accessory keys at virtually any location and in any desired number of switch modules. The keyboard switch module (45) or connectors are of the tongue-and-groove type, especially dovetail connectors formed by flanges (75) and recesses (77) on the modules. The modules include means for effecting an interference fit to interlock adjacent modules. Preferably this interlocking is achieved by means of crush ribs in the connector recesses which engage the connector flanges.
