摘要

The system has a magnetic structure with magnetic poles (5, 6) arranged in an alternating manner. A hall switch (9) and the structure are movably arranged to each other, where the structure forms a band (3), which comprises a carrier band, on which the magnetic pole is arranged. The band also comprises a covering band (7), which covers the magnetic poles, where the carrier band and the covering band comprise a part of plastic. An electronic circuit (11) is attached at the hall switch.
