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.

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).
