Mini Happs Competition pushbuttons?

[Jakobud]

I was in Boomers yesterday checking out some of their games and there was this on baseball game in some generic Dynamo cabinet and it had some normal Happs (or so they appeared to be) Competition pushbuttons (convex shape).  But there were also a couple buttons on the control panel using these much smaller competition like buttons.  They looked and felt exactly like a Happs Competition except they were about 1/2 - 5/8 the diameter of a normal Happs Competition button.  Does anyone know what these are or where to get them?

Check out the crappy picture I took with my camera phone.  The green and pink buttons are normal happs Competition buttons.  The yellow ones are the mini ones I am trying to identify.  Like I said, they look and feel exactly like a normal happs competition except they are smaller...

Perfect for some sort of mini bartop arcade cabinet...

Maybe this.

It would make sense as it is smaller, has the same shape as the Competition and since it's only a momentary button it would be fine for start buttons.

Hmmm maybe... I don't really think thats it though, since this is a wood control panel.  I don't think that button would easily mount in a wooden one.

You would definitely have to route it from the bottom.

I'd also be interested in smaller size, quality action buttons.  I'd actually like them for a regular CP, simply because I'd like to put buttons closer together.  I know the larger, wider spaced buttons are "arcade authentic", but I'd really like to keep 3 buttons under my first, second, and third fingers  all at once without having to stretch my hand.
