Door lock cylinder, with a chip code recognition function, has a sensor at the key giving a signal to the sensor at the cylinder opening, for the control to validate before releasing a magnet switch

摘要

The lock cylinder for a door, with a chip code recognition function, has a knob at each end with a key opening. The sensor (42) at the key (4) sends a signal to the sensor at the cylinder opening (321) on insertion. Rotation of the key within the cylinder (3) releases rotation of the polygonal rings (322) to move the clip (323. This activates the control (35) to receive the key sensor signal for validation and release the magnet switch (36) or not as appropriate.
