My quadrifire Mount Vernon stopped feeding on the lowest setting, sounds like the pressure switch.

When I took a look at it there's a little micro switch attached to the side of the diaphragm box and it's loose and rattling around. I noticed that when I push the wires in a little bit, the micro switch goes in a little bit and I can hear it click.

Is that normal or is this part broken?

I cannot imagine it is normal to be loose, being a sensitive sensor.
Okay I have confirmed that this looseness does in fact affect the function.

Do I need to replace it with this exact part or is there a better air flow sensor available? Will any of the quadrifire air flow sensors work?
 
I do not know if there is an interchange. For now, you could try holding the loose part exactly where you think it should be, then glue it with a glue gun.
