Quick Connect Contacts

Sep 14, 2012 17 Replies

I am looking for some type of contact to use on a front panel that would allow the momentary connection of a pair of discrete wires. I looked at the junction blocks used for speaker wire on stereos, but they are a bit large. This is on a handheld device.



It has been a number of years since I used anything like this, but I know I have seen this sort of contact. I just can't remember what they look like and can't find anything at Digikey or Mouser.

For some ideas have a look at

One of the spring-loaded terminal blocks from Phoenix maybe?

Fastons work pretty well.

Thanks, but I can't get this link to work. They say the site is down for maintenance. Maybe they don't allow access from the US?

That is not quite what I'm looking for. I know this is a bit hard to describe. I'm looking for some sort of spring loaded device that will let me connect a wire from a pickup that is not in an instrument. So it will have a pair of wires hanging from it. The connection is just momentary for a reading. I suppose we could just have a pair of exposed pads like nail heads. I thought a spring clip might be better.

Would one of the 0.75" dual banana jacks be too big? The nice ones have a screw binding post that you could use to connect wires to.

Oh. We use some terminal blocks that you just stick a wire into

You push on the orange things to open up the spring clamp doobies inside.

Fhanestock clips?

A pair of alligator clips mounted to the frontpanel?

Stef (remove caps, dashes and .invalid from e-mail address to reply by mail) Gravity brings me down.

Assuming safety isn't an issue...

Use steel contacts (plated if you like) and a couple of small magnets to clamp the wires - maybe the small 'notice board' types with a plastic handle.

Or use plated PCB pads with magnets fixed underneath, and that way your opposite polarity free magnets will centralise nicely on top.

Or tension springs which you bend sideways to open a gap to clamp the wire.

Cheers

I'm getting an education. I never knew the name for these things although I still don't know how to pronounce it. They don't quite do the job though. This will be the front panel of a consumer device and it will need to look attractive.

The closest thing I have seen are the spring loaded connectors they use for speaker connections on the rear of stereos. They are pretty close to what would work, but they are large. This needs something like that but smaller.

Thanks to everyone making suggestions.

Naturally, and obviously hoo-boy...

Those look remarkably similar to these
