Some buttons trigger the “walk” sign but don’t actually change the traffic signals for cars.
Some buttons are placebo, perhaps with a secondary function of emitting a loud tone to let blind people know the walk signal has turned on.
Some buttons trigger the traffic lights to stop.
Some buttons turn the traffic light to a 4 way red light.
I have encountered all these types of buttons on the east coast of the US in various states.
