ELEKTRONISCHER SCHLUESSEL

摘要

The electronic key has a drive head and a turning blade for inserting in a rotor of a lock. The key has an intermediate zone, on the edges of which there are retractile contacts charged by springs in corresponding housings. These retractile contacts are joined to conducting plates that come through the head from the electronic circuit integrated in the drive head itself. On the insertion and turn of the key in the lock these retractile contacts enter into connection with fixed contacts of the corresponding electronic circuit of the lock that are included in the interior wall of an annular extension of the stator in front of the rotor of the lock.
