or switches that use standard "Cherry Type"

About halfway down the page, just below the yellow (and double width farther down): http://www.smcelectronics.com/swkey.htm
They would be for a Leopold in my case. I don't know what they mean by "standard." The stems seem a bit short to me. I wouldn't mind going lower profile if they'll work.
What I'm really seeking are any decent roundish-on-the-top sphericals, like these vintage ones (that are pictured for just the purposes of color samples, unfortunately, and not actually available):

Versus something like these more squarish sphericals, for example (do not want):

Thanks for any help.
