It works for my subzero fridge, but it's not a perfect fit.  The light switch does fit in the slot, but the end with the 2 prongs is wider than the original switch.  The panel on top of the fridge doesn't fit correctly after installing this.  There is a slight gap as the panel can't be pushed in all the way.  Otherwise, it works...just a different look (the part of the switch that goes in and out is wider than the original switch as well).
