DEVICE FOR DATA INPUT INTO A PORTABLE OBJECT

摘要

The invention concerns a device for data input into a portable object, in particular a watch, with display screen comprising a control button (1) consisting of an elastic matrix (2) wherein is housed a permanent magnet (3) and a positioning analog magnetic sensor (4), with Hall effect for example, arranged inside the object opposite to and spaced apart from said control button (1), said sensor being adapted to measure the movements of the magnet (3) in at least one direction for data input. The control button (1) is arranged in a blind housing (7) of a non-magnetic wall (5) of the object structure, to be mechanically uncoupled from the sensor, said wall not in contact with said sensor acting as sealing protection for the sensor.
