Front panel Switch series for 1-row front panels IX01xx as above-adaptable accessory including induction loop / ring line for hearing aid wearers, which transmits the audio directly to a suitable hearing aid and makes it easier for the visitor to communicate with the resident. During operation, this ring line emits an alternating magnetic field, which generates an electrical voltage in the receiving coil of the hearing aid through electromagnetic induction, the course of which is the same as that of the audio signal. In the hearing aid, this is amplified by the audio amplifier and passed to the wearer's ear via the earpiece. In order to use such induction loop systems, the hearing aid must have a so-called telephone coil (short: ""T-coil""), which absorbs the alternating magnetic field of the induction loop. The hearing aid microphone is usually deactivated when the telephone coil is used. To be completed with the flush-mounted housing IX9156 or surface-mounted housing IX9160A. Dimensions: 150x129.5x2.5mm.
