ABSTRACT:
An array of curved metal strips is supported over an array of conductors, and a key is supported over each intersection of a metal strip and a conductor. When a user depresses a key, a metal strip is pressed against a conductor to make an electrical connection. As the metal strip is deflected by the key, it snaps or buckles, providing tactile feed back to the user. Each curved metal strip has a tine on one end for coupling the strip to a conductive member on a substrate that supports the strips and the array of condutors.
