The PKW21 sounders are used in rail vehicles. The products installed in the door area warn passengers of opening and closing doors by means of various beeps. Thanks to the similar construction of the Presskey push button, the PKW21 sounder fits well into the overall picture of the vehicle along with push buttons and signal lights.
