| 摘要 |
The invention concerns a security motion sensor (2, 3) comprising a support (8) and a front surface (9) wherein slides a key (4) along an translation axis XX' from an initial position to a final position, including at least an electric contact (6) actuated along an axis YY' substantially perpendicular to the translation axis XX'. The invention is characterised in that it comprises transfer means (5) actuated by the key (4) along the axis XX' capable of acting on the electric contact (6) along the axis YY' by being brought closer or spaced apart. Said transfer means (5) is a deformable elastic blade (17) adapted to transform the force generated by the translation of the key (4) into a force applied to the electric contact (6). The invention is applicable to keyboards.
