The font declaration is still wrong and it’s more likely you get Latin 
Modern Sans
in your document which is used as fallback when the requested sans serif 
font
wasn’t found.

You can see in the attached document the output from the following example.
Only the first font defintion loads Futura, the third falls back to 
Latin Modern
because there is no font with the name “file:futura”.

\definefontfamily[realfutura][ss][Futura]
\definefontfamily[fakefutura][ss][Latin Modern Sans]
\definefontfamily[filefutura][ss][file:futura]

\starttext

\switchtobodyfont[realfutura]Is this Futura or Latin Modern Sans?

\switchtobodyfont[fakefutura]Is this Futura or Latin Modern Sans?

\switchtobodyfont[filefutura]Is this Futura or Latin Modern Sans?
