Well, when I look it up on the internet it's called a disconnect switch. There
is something definitely wrong somewhere when the unit will NOT shut off unless
I pull this switch out.

It is just a pullout disconnect. The HP running all the time might be
the thermostat. That is what I would try first. Is it a solid state or
old school with a mercury bulb? If it is solid state try pulling the
batteries and see if it keeps running.
