Product review (5 stars): Replacement Jenn Air Infinite Switch (top burner switch) 700855K
MyJenn Air stove top is over 30 years old and still operational and I had been searching for this replacement switch.  I ordered one from another source and had to return it as it did not fit.  I was so excited to find the perfect match.  I recommend anyone to use Amazon for all their needs.  Very satisified.
