[MakeLV] thin SPDT tact switch

[Josiah Ritchie]

Yeah, that's not really made for modding. Have you considered replacing the
whole unit instead of modifying it? A 3D print job or some sugru could
result is some nice  results to drape some leather over in such a way that
the switches could be invisible under the leather. This looks like a neat
project. What are the buttons going to accomplish and how are you going to
connect them to whatever you are controlling?
