My Kitchaid in-sink Garbage Disposal unit won't stop running. It's the type
that is normally activated by turning the stopper. When the stopper is
removed, the unit stops running.
Now I can only shut it off (and turn it on) by the switch under the sink.
I have cleaned out the unit but it stil keeps running.
You already know the switch is stuck in the on position. Did you try turning
the stopper 90 degrees and trying again? The switch is not readily visible,
but you may be able to find the lever that trips it. It may be worn or the
stopper end is worn.
How old is the unit? Some have 5 year, others have 7 year warranties.
Model#? Approx age?

Have you checked yours warranty, some have extended warranty.
Very possible the switch that the sink plug actives is bad.

Had the same problem with my Insinkerator. Locate the switch (plunger)
inside of the unit. You can spot the location by looking at the unit
underneath the sink, by where the cover resistance increases and then inside
by feeling around with your finger. I used a tooth brush soaked in various
cleaning materials and brushed away at the plunger Kept pushing on it until
it loosened up quite a bit. The alternative is to replace the
