I think, unless the lighting is really messing with the color that the green in this switch is a much lighter green than the green linear switch. It's probable that it's a strange fake alps.
Not necessarily true. I had a Dell AT101W that had switches that were more of a gray colour than the black I had seen in other AT101/102s. Upon disassembly of the switches, I found that they were completely identical. So I'd say that the above are linear switches, and as itlnstln said, the seller is using 'clicky' as a generic term.
