Deaf loop / switch with induction amplifier for carriers of hearing aids

If you want to equip a switch with BehiG-Komform, a hearing loop is essential (requirements according to standard SN EN 60118-4: 2015+A1:2018).
Extract from the UVEK Ordinance on the technical requirements for the design of public transport for people with disabilities: 151.342, Art. 5, Paragraph 7: In switchgear systems with intercom devices, at least one switch must be equipped with an induction amplifier for the hearing impaired and marked accordingly.
An induction loop, also known as a HearingLoop or T-Loop, is an assistive hearing system that allows people with a hearing impairment to access facilities. It picks up a sound source and transmits it directly to a hearing aid without background noise. The presence of an induction loop should always be indicated by the sign on the right.
