Abstract (en)
[origin: EP0812971A2] Two or more permanent magnet pellets (4) are mounted in the shank (2) of the key, and a lengthwise profiled groove is formed in the front and/or rear of the key. One at least of the grooves forms a control groove (7), and is widened and deepened (9) between adjacent pellets. The groove cross-section can be a scalene right-angled triangular, whose hypotenuse is formed by the flat side of the key. The longer of the other two sides forms a groove flank sloping from the flat side to the groove bottom, which forms the shorter side. On the opposite side of the key there can be a further lengthwise groove, whose bottom is parallel to the flank of the first groove (7).
