Had one similar to that in the glove box of my '69 Chevelle to disable power to the updated HEI distributor.

HEI was the acronym for High Energy Ignition which was introduced by GM in 1975. It was their entry into the electronic ignition era, and was an easy retrofit upgrade to earlier, contact point equipped ignition systems, on both small block and big block Chevrolet engines. The HEI distributor itself had a single wire power feed, and by installing a simple inline switch the ignition system could be disabled at will. A poor man's anti-theft device, as it were. I must have installed several dozen back in the day.
