I have no idea, please help. Identifying a component and how to fix.

Ok, so, I have a basic understanding of electronics, be bear with me because my education is in English literature. I just tinker a lot, and mostly with vintage stuff.

So, I recently restored a Chevrolet truck from the 50s and I bought this radio that was designed to look like the original, yet be capable of am/fm/bt. Just last night one of the buttons stopped working, and so I took the face cover off and the picture that follows is what I found inside.

One of the little trip-switches for the analog buttons fell off and because it’s so small I can’t seem to find it anywhere in the general vicinity to solder back on. What are these things called so I can buy another and repair this radio after dropping almost a thousand dollars on it?

Do a 3D print design or is part you are talking about part of the electrical
contact in the switch ?

Obviously you have shaken the radio, given it a little whack on a bench, to
shake loose the part if its hung up in a wire/case inside radio.....? If its magnetic
swept the carpet or floor with a magnet.....?

Regards, Dana.

Right, the way it works is the little switch solders to the circuit board as an electronic component. The little black tab hang tiny off is what the analog button pushes and releases. So, I think there’s some electronic stuff going on inside the missing part.

I did tap it a little to try to dislodge it from the interior of the radio, but I didn’t want to be too aggressive.

The switches are side actuated tactile switches.
You might get lucky by searching google images. Try tactile switch and then side actuated tactile switch.

Here is a similar style for example:

Looks like a proprietry line of tactile switch.
I had similar with the receiver on a Qanum R/c data device.
Only way is to get exact measurement of the switch body and the terminals (outline drawing including the depth etc.)
Then do a search for pcb mounted side mount tactile switch, found mine with a seller on Ebay in Aus.
Next hurdle is to get the little mother back on where it belongs.
I have some 50 years experience and it was a job and a half.
Way I approached it was to clean pcb of excess solder using wick and plenty of flux.
Bought some solder paste, applied to the four PCB pads, place and retain the new switch with a largish toothpick, apply heat via a good soldering iron.

Place I bought mine (they have others as well)...

Hello,

Here is a little google image search that @Martaine2005 recommended:

side actuated tactile switches - Google Search

Compare the size of the part with some datasheets in the search.
