How about a breakout board for this mini push button switch:

I am aware of your breakout board for the LED switch, but I don’t want a lit switch.
The mini push button does not reliably stay in a breadboard. The breakout board I have in mind would
attach and electrically connect to a breadboard using break away headers:

I’ve not had any problems with any board not attaching securely to a breadboard when I use these headers. That is true even when I run jumpers under the board.
You might consider a double switch board with separate circuitry for each switch.
On a separate issue, when you identify a part as being in the Eagle files, could you be certain to identify the file name or provide a link to it. I have searched unsuccessfully for the Eagle file on the push button.
