54-key integrated keyboard assembly with On/Off rocker switch for IBM Electronic Typewriters models 50, 60 and 75, IBM's first typewriters that were electronic rather than [electro]mechanical (ie, able to perform some amount of internal processing via electronics than rely on mechanical elements). The keyboard assembly seems inspired by IBM Card Punch keyboards but uses a series of magnetic reed sensors for key-stroke sensing. The keys can lock, which requires the host typewriter to unlock them.
