In germany things are worse though: sometimes no feedback at all, feels like a hard cover plastic without any feedback at all. It seems to register touch (some do have a "please wait" lighting up when you touch it).
For the blind there is a nub hidden underneath. It has an embossed arrow on it and because of its horizontal orientation it can point precisely to the right direction. It vibrates when it's safe to cross. However this is the place that stays wet the longest after rain and where people smear their chewing gum and the cleaning personal doesn't even see it. I still enjoy the buttons, so I don'- have to focus on the lights all the time.
edit: when you don't know about the nub for the blind, there is no arrow indication at all. When standing on an isle in the middle of a street and there are two buttons on one pole opposed to each other, I never knew which to press: the one facing where I want to go, or the one facing me while I face where I want to go (I think it's the latter)
