摘要: A modularly expandable keyboard has expansion modules which are integrated into an elementary keyboard by locking tongues inserted in depressed tracks in the modules and held in place by detents in the attached modules. The detent mechanisms are formed integrally with the housings of the modules and are unstressed when fully engaged. An electrical interconnect plug integrates the electrical busses of attached modules. Modules can be attached to either right or left and additional modules can be attached to already attached modules indefinitely.
