The switches I pictured are the ones that seem to be mentioned here. I thought "Carling" which is the name brand. "Contura" is the name of the product line developed by Carling, so "Carling Contura Switches."
It's nice to see a place that offers new Switch Covers. All of mine work, but the labeling is long gone, faded away. It'd be nice to get them readable again, and I like the idea of minimally invasive replacement, leaving the switch in place.
