These metal ball tactile switches are very versatile. They can be used like any other momentary tactile switch and are great for adding a sleek auxiliary for a CFX or Proffieboard. The drill bit you would need to use if you are adding this switch to your hilt would be 5.5mm wide, that's assuming you have a holder to support the switch.
