Product review (5 stars): Fixed my problem!
Exactly as described and just what I needed.  The original "rocker" switch that controlled both the vent fan and the oven light had broken and that style is no longer available.  This controls just one or the other - in my case the fan - but that's all I really needed.  Easily installed.  Works great.  Happy that I don't have to replace my stove because one little switch broke!
