"Spring" connectors

Do you mean Fahnestock clips? I think they are still available.

es in those "100 Electronic Projects" kits that we used to play with as kid s? You bend the spring, insert the wire between the coils, and you get a ni ce temporary conductive connection when you relax the spring. Does anybody know where I might be able to source those?

ve searched around but are struggling to find a suitable source. We would l ike to use them in a test fixture if we can find some. Thanks!

Hmm google nickle coated spring.

Those might be better. (I think he just wants an extension spring.) GH

Thanks for the responses. Fahnestock clips are not quite what we are looking for - we need to temporarily attach 36 gauge wires to a test fixture. Fahnestocks appear to be made for something much larger.

Here is the link to the Sparkfun parts:

Unfortunately they don't sell them anymore. They pointed us to their source in China with a "Good Luck".

This British vendor has some.

Hobby shop, railroad springs maybe.

We use to buy silver plated phosphor bronze springs from Small Parts. I miss that place.

Huh, so in general it's best to start with, "we need to temporarily attach 36 gauge wires to a test fixture." We are thinking of springs.... and then you'll get some more ideas... rather than just being stuck on springs.

We use some nice Phoenix machined connectors, 2.54 mm spacing. Green plastic. (I can look up the part number tomorrow.) They have flat jaws and a small screw, so don't crush too much. (I like the bigger Weidermuller (sp) ones but they have serated jaws.)

Probably a Keyelco / Keystone part.. I'd check there.

I looked at this page. Just a few minutes ago I got an email saying this item is "trending". lol

They're just tension springs. They were pressed into a hole in thick card. You could bolt or rivet them to an insulating panel.

I bought catalog and custom springs from both Lee Springs and Century Springs many times at my last job, both were great to deal with and have online catalogs. Both offer a selection of materials and plating options, and you can probably get the ends ground flat if you really need that. I think the sparkfun page said that they were 0.25" od by 0.375" long. You'll have to measure the wire diameter from an old one if you have any, or guess. Buy 1000 to get a great price, and start selling them on ebay in packs of 50 :-).

Thanks to all for the kind responses, ideas and links. This is a great forum with a lot of helpful and knowledgeable folks, in spite of the rather low SNR for off-topic posts.

It's kinda like sitting in a bar full of engineers - this table is pontificating on politics, that table is debating climate change.... Occasionally even a conversation on electronic design comes up. :-)
