The plastic around the winding and plunger in my door bell melted when
the door bell button got stuck in while I was gone. The button is 2
years old. I can get another, but it could easily happen again. It
seems like it could be a fire hazard too.

Is there any kind of mod I can do to keep the bell from melting again
if the button sticks? Something I could add that would make the bell
go ahead and complete it's 'ding-dong sequence' when the bell is
pressed, instead of waiting until the button is released before it
'dongs'?
