<p>The knob cylinder has knob shaft (7) or spindle that is rotatably coupled to locking cam (5) of locking cylinder. The locking cam is reset in reference position. The rotationally-operating magnet discs (6,10) are arranged on the knob shaft, which are alternately oriented with opposite poles. A lock cylinder housing (2) is rotationally held on each magnet disc. The magnetic polarities are selected, so that the knob shaft connected to magnetic disc is constantly rotated back to normal position.</p> |
