This is a simple switch holder that you can really use for anything you want.

I personally use it to test stability for my custom keycaps

Normal version switch hole size 14.01mm by 14.01mm so the switch may be a bit tight but for me its perfect for testing.

Better tolerance version uses 14.26mm by 14.26mm for higher clearance so it doesn't squeeze the switch too much.

If you are unsure and have sand paper try 14.01 then sand it down if its a bit too tight but well its up to you what you want.
