Looking for a “smaller diameter” plastic mushroom style steering button that I want to use a bump up button. What is the smaller size (diameter ?) and who offers them? I looked at Summit/ Jegs/ Biondo and don’t see what I want as the button diameter information is not listed, only the mounting hole size (5/8”).

I found some nice loooking button on EBAY with aluminum button. About same as mushroom but little smaller and since for minor stuff like bump down and chute activation I did not see need for high dollar like B&M piece. May or may not fit your needs.

It's not plastic, but the Biondo is probably what you're looking for. They used to call it the "small mushroom", now it's "standard".

I’m looking for this in a smaller button diameter. The pic is Biondo 1-1/8” button diameter. I’m looking for slightly smaller, like 3/4” to 1” diameter. Don’t know who offers this, or if someone does.

Pull the button off and have someone turn it down to the size you want.

What about Biondos green button

Look at these. Is this what you're looking for?

Made more for LL or TB application and much smaller than desired. I’m considering trimming a larger one down now.

I’ve looked at those…no cap diameter size listed, only hole size needed to mount. Anyone know what diameter size these are??

Ebay item # 256253247933
says 5/8 hole roughly 1" button, have different colors as well.

Hi, maybe check with W.W. Grainger, Newark Electronics, Digi-Key, or Mouser Electronics for some sort of 16mm or 22mm switch.

They all have pretty good search engines.

Seems a little bit bonkers to me that a 1" button is OK but the extremely common 1.125" button is a bridge too far.

There are certain things that I am particular about though, so I can understand it.

Those eBay buttons with the etched labeling do look nice, and aren't expensive.

^^^^^^^ Agreed, but I prefer smaller and purchased this 0.93" one.

I should buy some of either these or the large aluminum buttons without anything on them. I could mark them with my laser. Bump down could be a "DOH!" button.

I was told once to put a "Lose" label on the bump down since I normally bump red
