This is an adaption of the listed design of juh. Because the push buttons I had are different I had to modify the design but it kept the original idea. The push buttons I used are pretty common and cheap. They come with different color buttons. I bought 25 for just 5 Euro.

Only thing to modify: You have to flat the legs. No soldering necessary

The intention is for the 2.6 mm flat plugs of Fischertechnik. Similar round plugs of Märklin are also very common in Germany. They have the same metal part and will fit just as well.

The two parts should be very tight so there should be no need to glue them together. I kept the Fischertechnik spacing. There perform nicely as end switches.
