Method and device for transmitting electrical power and/or signals between a wall and a leaf pivotable relative thereto

A device for transmitting at least one of electrical power and signals between a wall and a leaf which is mounted so as to pivot on the wall, the device comprising:

• a transmission device which comprises,
• a device for detecting a magnetic field strength in surroundings of the transmission device, the device for detecting a magnetic field strength comprising a magnetic field sensor which is designed as at least one of a reed switch and a Hall sensor,
• a coil arrangement arranged on a side of the wall, and
• a coil arrangement arranged on a side of the leaf;
• a coil arrangement comprising a coil housing and a coil winding;
• and
• an electrical circuit arrangement comprising a board,
• wherein,
• the magnetic field sensor is arranged on the board,
• the board is arranged on an outer side of the coil housing,
• the board comprises a transmission and/or receiving unit of an opto-electronic signal transmission device, and
• the opto-electronic signal transmission device is provided as a part of a control loop for controlling power which is applied to the coil winding on the side of the wall which based on a power requirement of the side of the leaf.
