ABSTRACT:
There is provided a device for the contactless coupling of control and output currents between the electronic elements on a locking cylinder and the electronic elements in the key of an electro/mechanical locking system. The device is characterized by a multiple coupler consisting of a part integrated in the key, preferably in the handle of said key, and a part disposed on the periphery of the locking cylinder, so that when the key is inserted in the locking cylinder, the two parts oppose each other at least at one point in such a way that contactless electrical coupling of the control and output currents is possible between the electronic elements on the locking cylinder and the electronic elements in the key.
