Separating 5k windows switches?

[Wallace White <wallace@remdesign.com>]

I took the driver's window switch assembly out today, in hopes of
finding a few dirty switches to be the cause of lackluster window
performance. I've run into a small problem: I can't get the switches out
of the large plastic trim piece. Sad but true. 

How do you separate the switches without breaking them or the trim
piece? I can't see where they're being held on. Thanks.
