your lever would need a capstan circumference of 5 inches or take multiple revolutions... (that 12cm)..
how about a pully , 2 housing frame stops, and a loop of cable.. will do the job, I suspect ..
use a bare cable run and attach a ball to it to pull /push
or a big ol' stingray shift lever to pull .. with the distance to lever pivot say 3~4x the cable pull ..
of course, a servo motor could turn that capstan and then you just need a rocker control button
or up/down pair. and a battery ,,
