I have a two door bell system. One works fine, the other holds the plunger against the bell continually. They are on the same transformer. I already replaced the switch. If the bad bell wire is attached to the good bell post the symptom continues.

I suspect you have a 16-volt 10va doorbell transformer. If you do, you should upgrade to a 16-volt 20va or 30va transformer. A 10va transformer isn't enough for more than one chime.
