ABSTRACT:
An IACK keypad with independent key regions arranged in an array of multiple rows and columns, and combination key regions defined between rows and columns of the array of independent key regions. A trace matrix underlying the keymat either includes, in addition to normally isolated column traces and row traces underlying the independent key regions, trace extensions extending from the row and column traces to underlie the combination key regions, or additional row and column traces underlying the combination key regions and tied to other row and column traces. The trace extensions extend to within a contact region of an opposed electrical contact, such as on a snap dome, beneath the combination key region. Independent and combination key snap domes are constructed to insure singular tactile feedback during combination key operation.
