Sorry to revive such an old thread, but I was wondering if anyone who has tried this specific repair could explain how to separate the plastic segments in the switch body? I was able to slide out the metal tabs on the sides, then the segments came apart easily in groups of two, plus one with the metal face plate. But I haven't been able to separate the groups of two. There are plastic tabs on the side, visible in the pictures above, and I can pry them open, but the other side of the group appears to be held together with something else that I can't figure out.
