摘要 An apparatus (10) for adapting the primary control button (23) in an elevator control panel (4) for use by handicapped people who are not able to normally reach the buttons (1-3). Apparatus (10) includes an auxiliary control panel (12) which mounts a plurality of auxiliary buttons (1a-3a). A first link arm (28) connects each of the auxiliary buttons (1a-3a) to one end of a pivot rod 22. A second link arm (30) connects the other end of the pivot rod 22 to a false primary button (1f-3f) located immediately in front of the primary buttons (1-3). The primary buttons can be actuated either by pushing inwardly on the false primary buttons (1f-3f) or by pushing inwardly on the auxiliary buttons (1-3) and causing rotation of the pivot rods (22).
