V1 - Front-panel push button fails
The V0 boards produced have non-functional front-panel push buttons. The same model is used in the V1 design.
Likely the switch type is not made to be washed.
See C1 (page 6) and E1 (page 7) of the datasheet (attached).
- C1: following the soldering process, do not try to clean the switch with a solvent or the like.
- E1: Foreign matter invaded from outside. Since this switch does not have sealed structure, it may have contact failure caused by the dust from outside up to the environment.
