What is this type of spring called?

[rea5245]

I'm working on restoring a Heathkit H9 terminal. There's something the instructions refer to as a "tension spring" that looks like a springy piece of metal, that slips into a groove and holds the bezel in place.

Googling for "tension spring" gives me a very different type of product. What is the right name for this?

Thank you.

It's a sort of flat spring, you'll probably have to make them if you need any.

Might be called a wave spring: https://www.mcmaster.com/springs/linear-wave-springs/

You can cut from that or from a disk spring: https://www.mcmaster.com/springs/corrosion-resistant-curved-disc-springs/

It's a small example of a 'leaf spring' isn't it?

P.S. You might be able to cut sections from an old clock spring.

Not sure if this helps but over on the HPAK group people often suggest using a piece cut from a feeler gauge as a replacement spring in buttons. This might be easier to acquire for your repair.

In metal picture framing, they're called "spring clips" and are used in the same manner. Easiest way to get a few is probably just to buy a cheap picture frame at your nearest discount store. You likely need to cut them if you want them that short, but I suspect the longer version will work ok too.

Alternately, you could use anything slightly compressible to serve the same purpose...you just need a fit snug enough to not rattle when you're done. Cardboard, cork, window gasket, etc.

I have lots of leaf springs for framing.  I'll be glad to share some for the OP.  However, those springs do not hold tight tension.  I'm afraid they'll come lose and cause secondary problems.

More I look at it, I don't think it's critical what you use.  It's just a shim.  Even a rectangular cut cardboard might work....
