I used the following TC011 switches with the 4 button boards I designed a while back, attached in the button's description:

The small boards are mounted on four M3 standoffs each with 15mm spacers. In total, it's 16 of these small boards, an additional matrix board for the shift registers and eight ribbon cable strands with 20pin connectors. My initial thought was, that these small boards would be very versatile (which they are) and ultra-cheap in production as a 20 pack of small PCBs is a fraction of the price of one single large PCB. However, this also meant, that I needed 64 standoffs on the back side of the front panel to mount the PCBs as well as many IDC connectors and it also was a lot of work to mount everything. In the end, the additional price for the front panel was about the same as a larger PCB would have been.

 

I also went for single colour buttons, whereas dual colour would have been nicer.

Thanks for the explanation!
