Hi Guys,
(see photos)
This is a ceramic puck with (3) solder contact points. Inside, it has a small winding of wire around what looks to be a paper or cloth insulator. The insulating material is wound around a flat metal core.
This part is found in a 1936 Mills "Do Re Mi" amplifier. I've replaced all the resistors and capacitors, and this is the last part to confirm working before I can test the amp.
*Other notes: I noticed that some of the windings may have fallen off the paper material and now sit directly on the flat metal core. I would like to first know something about this part. Most importantly, I need to know what it does and whether I should attempt to fix the windings - moving them all back onto the insulator.
Precision resistor? Small value capacitor?? Thanks.

So it is fair to say that this switch is good if the wire has continuity? What are your thoughts on the apparent insulating material, is it truly there to provide functional insulation? I'm not sure whether it is paper or asbestos.
This thing has an adjustable contact point. If it were a switch, that would mean that the flat metal core should change shape and interrupt the flow of current in the event that the circuit parameters became harmful, right? What are your thoughts on the few windings that are in contact with the flat core? Thanks,

It needs to be insulating, otherwise it will short the turns; it is probably a mica composite foil
Yes, it is certainly a bimetal strip.
The start or the end is probably already connected to the core, but for the rest it certainly needs to be insulated
