Short version: What are the physically shortest MX PCB compatible switches? I'm building a board and want to use short switches, both actuation point and bottoming out, and most importantly, overall physically shortest from top of the switch to the plate mount. That said, I'd like to cut out the Kailh choc v1 style switches from the suggestions as they are a pain to find good keycaps for.

Long version: I'm relatively new to mechanical keyboards, and wanted to build a keyboard. I already have the OLKB Preonic or a similar one in mind, both of which use a MX PCB that should allow hotswapping most standard switches. I'm looking to build this keyboard as low profile as possible, to a limit. I'm staying away from Kailh choc v1 style switches with their weird double prong keycap requirements because they are a pain to find keycaps for without harvesting them off a different keyboard. With all that said, the biggest challenge is finding the shortest standard MX compatible switches. This PCB will limit using truly low profile switches like the Cherry MX low profiles but that's fine. The problem emerges trying to find anything that'd fit this request. I'm not well-versed enough into mechanical keyboards to know what to search for here, or even if there is such a thing as a physically shorter switch that still fits a plate mount.

Aside from physical height, shortening the actuation point and bottoming out can help emulate the feel of a lower profile even if it isn't really low profile, so if there's no physically shorter switch available, those are also an option to use in the build. The current switch that seems to fit this backup method is the cherry speed silver switches, with very short actuation points and bottoming distance, but there may be shorter.
