Product review (5 stars): Same switch used in many SUB-ZERO refrigerators
Used this as a replacement light switch in a 10-year-old Sub-Zero model 632 side-by-side refrigerator. Completely indistinguishable from the original switch. In fact I'm convinced that it probably came from the same manufacturer Sub-Zero uses. Also looks like it would work for the adjacent fan switch if needed. Super easy to install: just remove the upper grill and push the tab on the right side in while prying from the bottom working the lip of the switch with a thin putty knife (easier than it sounds).

A service call would've been a minimum of $120-140 plus the cost of the switch which I'm willing to bet a Sub-Zero repair service would have charge $25 to $30 for.

You can't beat the price and quality of this switch and standard shipping was super quick!

Additional note: this switch looks to be fairly common in a lot of different refrigerators not just Sub-Zero.  Something worth considering if you're looking.
