There is no documented origin for this clip beyond its user-generated soundboard upload, so its history is really the history of a whole genre of tiny utility sounds. Streamers, podcasters and bedroom producers pass around sub-second connector clicks, switch snaps and plug-in pops as shorthand for getting the setup right. The German word richtig, meaning correct, suggests the uploader labelled the satisfying version of the noise, the one that sounds properly seated. It survives because every creator who has ever fought a loose cable recognises the feeling instantly.
