Keyboard having switches with tactile feedback |
摘要 |
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 feedback to the user.
