take a look at type-imp-plex.mkiv (just remove the \s! in your case)

basically you define two typefaces: normal and light and then just 
switch between these, as in:

at the top of your document you say

\usebodyfont[plex]       % preloads
\usebodyfont[plex-light] % preloads

\setupbodyfont[plex]     % enables main font

and after that

{\switchtobodyfont[plex-light] .... }

will do a consistent switch
