These are the correct size that several 3D printed projects I've seen and are a good size to design for in your own projects.

Needed this for a guitar pedal and it works great

If you glue the switch into place, such as a metal panel or wood cutout, carefully control any adhesive away from the slide and inside contact areas. This should be obvious, but it happened to me.

Most work and are great, but several are DOA.

Nice little switches for breadboard projects.

I use these for small electronic projects or repairs. Nice tall switch. The work great for my uses.

Lots switches for cheap. Have used two so far. Worked fine.

Be careful. The metal tabs that hold the body together will cause a short if you mount these on a perfboard with though vias.
