The usual method is a push until it clicks…

There is most likely an under cut in the cap that fits over a ridge on the post…

allowing it to be pressed on and later pulled off…

PP thoughts only, not an avionics guru…

You can get them on Digi Key for a couple of bucks.

Depends on the switch. Switch caps  5/16” or larger often snap on or screw on. Smaller ones with smooth shafts are designed to be glued on or they come off and get lost. Super glue is commonly used - just use a small amount so it doesn’t ooze out and glue the switch shaft to the case.

An example of a screw on cap…

The Mooney electric gear switch… the post is threaded, and the big tire looking knob screws on the threaded post.

Same for the B-K autopilot red disconnect button.

Do you have a part number handy?  Or link?

Try this link, for switch caps in black: https://www.mouser.com/ProductDetail/Electroswitch/SW53AA2?qs=5muX3C0yOnj5E%2FJxlK6wTg%3D%3D&countryCode=US&currencyCode=USD

I didn't glue mine on as others have mentioned.  I'm sure it will fall off eventually, but it's been there for months with no trouble.  At about a buck apiece, just buy a dozen and keep spares handy.

This is the switch Mooney used in my 1994 M20J. I like it because the cap is small. Most miniature switches have larger caps.

My switch is good, but i need a new wire, the old one is shedding the outer layer. It's coiled up like a phone cord from the right yoke to the panel.
