ABSTRACT:
An input key positioning assembly for use in an electronic device having multi-input terminals therein. An input key formed with a flange is secured in a stepped opening in a first member so as to be downwardly and upwardly movable between the stepped portion of the first member and a second member formed with an opening smaller than the larger portion of the stepped opening and partially closing said larger portion of said stepped opening. A resilient packing positioned between the keys and a multi-input terminal is formed with projections for returning each key to its original position and for actuating the associated terminal. Said first member may be the cover glass of an electronic wristwatch with a calculator therein, while said second member may be a display plate for identifying the function of said keys.
