I was about to suggest that it looks like a capacitor. Singer used capacitors in some of their button style foot pedals. I have an idea that they may have used them internally in Featherweights but I'm unclear about that. Elna also used them in foot pedals and if I'm not mistaken in the machine itself near the electrical connections.
It looks like it may have connecting points on the left end where it might have been soldered.
