Push button with haptic feedback

Abstract:

Mechanical key design for keyboards often includes rubber or metal dome switches along with scissor mechanisms that offer a desirable feel and overall performance or achieve the key travel necessary to meet shrinking overall keyboard thickness specifications, but not both. Haptic feedback devices offer a user sensory feedback signifying a selection has been made without any physical travel of a keypad, but also may not offer the user a desirable feel and overall performance. The following describes in detail keys or push buttons that offer the user a desirable feel and performance, while meeting shrinking overall keyboard thickness specifications.
