A direct digital input and tracking system for converting mechanical movement input into a predetermined digital input for a microprocessor or the like comprising: a plurality of movable contacts in a predetermined arrangement, said contacts being moved in response to a sensed condition such as variation in ambient pressure; and a patterned array of coded, binary input lines located beneath said contacts, one binary line for each said contact, said binary lines being connected to a microprocessor or computer in preplanned fashion, whereby the sensed condition is directly converted into binary signals without need of any analog to digital conversion means, said sensed condition being variation in ambient pressure, said system further comprising a pressure sensitive bellows assembly having a fixed end and an opposite end linearly movable in response to said sensed condition, said movable contacts being fixed to said bellows movable end, said binary input lines being arranged in linear fashion beneath said movable contacts.
