Product review (1 stars): Cheap knock offs
NOT A WHIRLPOOL (FSP) PART!!

Cheap knock offs and not factory parts. I now have 5 of them that I can't use and are not really worth sending back. The contact part of the switch sits too far back in the range of the switch so it's prone to early failure. As a technician I would never use these at a customers house.  I'm sure they'll work for a while though.
