I don't think this is an off-the-shelf part.

I was looking to source them some years ago and I couldn't find them anywhere.

Probably it's easy to make them if you have access to a 3d printer.

+1 non standard shaft extender...

I've seen these made using shrink tubing to secure square stock to the switch shaft.

They are generally interchangeable among brands as long as the mating size is the same.  2.8mm and 3.3mm are the two common sizes.  Places like Mouser usually carry the caps,  some manufacturers include C&K, E-switch,  as well as Alps. Look at their catalogs and you should be able to cross reference what you need.
