We have been producing keyboards and HMI systems for aeronautics and aerospace for many years (airplane interiors, aircraft cabin management systems, passenger comfort systems, etc.). We are well aware of the needs of this sector, the strict requirements and the very high level of quality required by companies such as Boeing and Airbus, first and foremost the need for the keyboards to perform a great resistance to depressurisation, gravity and vibrations, in addition to having the least possible weight.
