Abstract
A lever (6) is pushed by a cam profile (23) formed on an actuating member (9) fastened to a movable body (12), the movement of which is to be detected. A cam (13) fixed to the lever moves a plunger (16) which actuates a position switch (33). There is interposed between the plunger and the switch an influencing member (22), the position of which is measured by means of a card (28) passing in front of photoelectric detectors (29). A processing unit (31) supplies, at the output, an analog or numerical signal relating to the position of the movable body (12), to its speed or to its acceleration.
