In addition to the usual Gira switches, rocker switches and rocker buttons are also available with large tactile symbols for the light, bell and door. They make life easier for blind people, or people with visual impairments. An acoustic element can also be used.
This means that not only will the doorbell and the opening of the door be clearly audible, but also the switching on of the light. When switching off, however, no acoustic signal will sound. This means that you can tell whether you are switching the light on or off.
