Product review (5 stars): Saved me $$$$
My Sub Zero fridge light was either not coming on when the door was opened, or the light was not shutting off when I closed the door.  I don't know what a Sub Zero service call would have cost me but it would not have been the $7.51 I spent for this switch!  It took a Phillips screwdriver to replace it.  The screwdriver was to remove the vent access panel on the top of the fridge.  Below the panel was this switch, replaces with no tools.  Probably saved me $250!
