Product review (5 stars): Do your research!
If you're looking for a replacement for your Subzero switch, make SURE its designed for Subzero. I bought virtually identical looking switches from Mouser and they didn't work. They were designed to let electricity flow when they switch was PRESSED, meaning the light would turn on when the door was closed, and off when it was opened. The exact opposite of what it needed to do. This switch worked perfectly. I wish I would have done my research and saved $20.
