[Accessibility] Mapping “turning nodules” in pedestrian crossings

Hi,

I currently live in London where there is a lot of pedestrian crossing 
with a special nodule / button hidden below a lot pedestrian crossing 
boxes. I would like to know how to map them well in OSM.

These nodules are shown in this video: 
https://www.youtube.com/watch?v=fRPWlBAgSnw They are small buttons 
hidden below the box with the button to call the traffic lights. These 
nodules turn when it is safe to cross the road.

The closest tag to it might be the vibration key: 
https://wiki.openstreetmap.org/wiki/Key:traffic_signals:vibration However, 
the word “vibration” technically describes something different (this 
nodule turns but does not vibrate, and it is positionated in a very 
specific location below). I thus fear that the “vibration” tag might be 
misleading, leading to people waiting with the hand on top of the box 
expecting it to vibrate in some ways instead of this particular behaviour.

I am not blind myself and have no idea how to map this in the right way, 
which is why I am asking in this mailing list.

Thanks for your help!
Regards,
Martin Constantino–Bodin.
