why do stop lights make you press the walk sign button?

This isn’t all stop lights. At many lights the button doesn’t do anything. But at some of them you do have to press the button. What is the purpose of making you press the button?

If no-one needs to cross the road, it would be pointless to stop the traffic. By requiring pedestrians to press the button you can keep the traffic interruptions to a minimum and only when there is actually someone who needs to cross.
