Product review (4 stars): Stove Burner Lights Every Time Now...
This is an exact genuine spark ignition switch for my (vintage) Tappan stove/oven/microwave unit. On my most used stove burner the old switch began to fault intermittently then quit entirely. I had to turn another burner knob to get a spark to light this burner. Anyway, I installed this new switch and my burner works every time again.

Since I always want to know why things go bad, I inspected the old switch to find it became loose within the circular spinning connector. Really, these switches should last a lifetime. Oh, well..I got 30 years use from the old one and expect to get another 30 years from this replacement.
