<p>The sensor (11) has three reed contacts with longitudinal axes arranged in parallel. Two of the contacts are arranged in a level. The sensor is practically operated by a magnetic field of a magnet (49), which is arranged at a movable part e.g. piston (45), and the third reed contact is arranged in a distance to the level of the other reed contacts. The magnet is oriented with respect to north and south poles in an adjusting direction. The sensor is equipped with a shielding at ends of the contacts in a longitudinal direction of the contacts.</p> |
