Abstract
A key has a varying response depending on the manner of depression. The key comprises at least a base and a switching element arranged curved relative to one another. Between the switching element and the base is a contact area where the switching element touches the base. When the switching element is depressed towards the base, the edge of the contact area between the switching element and the base moves along the surface of the base. The response of the switch is determined by observing the location of the edge of said contact area relative to the base.
