This interesting item controls the speed of a sewing machine. Not just any sewing machine, just the Concerto, Harmonie, 9100 series, 9400 series. When a special air foot control is connected to specific machine, and pressed this pneumatic transducer controls the speed be means of converting air pressure in to electrical pulses...! It often becomes burnt out with age, or even if the user runs the machine at too lower speed.

    Good pneumatic transducer replacement part. The fact the heat generated by my sewing machine light if left "ON" for a long time, is enough to melt/burn the pneumatic transducer is, however, a problem in my Singer sewing machine design. This is the second pneumatic transducer that I have to change... wish Singer would have come up with a better cooling design, possibly using an LED light which generates less heat.

    My old air transducer broke and I tried to fix the part but the plastic had gone brittle so happy to find that you can still get the parts, was easy to fit and kept the old machine running like new.
