ABSTRACT:
A retractable key assembly comprising a key top and an externally extending pivot arm. The pivot arm allows arcuate movement of the key top about a pivot axis such that the key top can be used in an upper, active keying position or stored in a lower, inactive position. The use of a pivot arm enables a lower profile keyboard when the keyboard is in the retracted, inactive position. Displacement of the internal actuation assembly allows the keytop to actually rest on the keyboard base. A translatable base member is useful to raise or retract the key assembly. The disclosed key assembly provides an aesthetic appearance and improved keying accuracy, relative to conventional keyboard arrangements.
