Narrative:

The first officer was not yet at airplane; so I accomplished the origination preflight. During the preflight; we were also dealing with several maintenance issues; including a broken vsi indicator and 2 of 4 brake wear indicators that were at or below the limits. During the stall warning test; I observed the aural warning and both push to inhibit switches illuminate; but with the distractions of the other issues; I didn't notice that the captain's white switch cover with the words 'stick shaker push to inhibit' printed on it was missing. It wasn't until after level off that I noticed the yellow cover showing [which should have been] behind the missing white cover. The switch still operated; just the cover was missing. I entered the discrepancy in the logbook and the switch was replaced at our destination.
