I’ve been looking for this exact connector but can’t figure out what these are called. The picture below is 4 pin one, but I’m also looking for a 3 pin one that is similar.
It’s a generic connector series that overseas shops sell on amazon for about $1.50 a pair. The magic search string there is “aviation connector ”
We sell a 6-pin version via sparkfun (1568-1759-ND) Unfortunately no 4 pin option here.

The four pin version was commonly used for the microphone connection on CB and other radios.
The Radio shack part is:
RS also has the matching panel mount jack.
I’ve never seen a three pin variation for sale at any of the usual US parts suppliers.
I’ve just spent two hours searching for this connector and finally came across your clue. With that it took a few minutes to track down examples on Ebay, including a 3 pin one. I used them in a one off project I built for a customer who has come back and wants another one. The original was bought from Maplin who have gone bust. Many thanks for the help!
I realize this is years later, however, I may have found possible alternatives. Hopefully this may help others down the line as well.
