24mm Arcade Buttons (OBSN-24 drop-in alternative)

Replacement/drop-in alternatives to Sanwa OBSN-24 buttons.  This design acts as a housing for a Kailh Choc keyboard key switch, and very closely matches the dimensions of the original Sanwa part (which are too small to fit a Cherry MX switch, unfortunately).

A 30mm OBSN-30 version is also available here!

Assemble is simple and straight forward.  Just insert the key switch from the top, aligning it such that the LED cutout of the switch is beside the flat portion of the housing, and push it in place.  Then, add the keycap/button top, and the button is ready to put installed into your setup.

Low profile and fidget version are also available.  The low profile version shortens the height of the threaded portion of the housing as well as the securing nut.  The fidget version replaces the securing nut with a covering, protecting the contact pins of the key switch.

Versions of the housing that are meant to be printed with and without supports have also been included.  Depending on the type of filament that you're using, you may one of them to be easier to deal with than the other.

Since the housings are quite small, the hotswap socket housings feature a cutout, which should give just enough room for the hotswap socket plus a wire.  Hotswap socket housings are available for each variant of the housings (supportless full size and supportless low profile, support full size and support low profile).

For installation and removal into an arcade stick/cabinet, there's also a removal tool.  The tool can be inserted through the bottom of the housing, allowing you to hold the housing in place much more easily while you tighten/loosen the nut.
