Abstract: Dome switches can provide inconsistent positive tactile feedback, particularly when depressed around the edges of a corresponding push button as compared to depression at the middle of the push button. Various arrangements intended to render push buttons that incorporate one or more dome switches more consistent in providing positive tactile feedback, while maintaining a reasonable ease and cost of manufacturing, are discussed herein. A push button with consistent edge performance using a single dome switch incorporates a hinge arm that spans button posts. This reduces or eliminates rotation deflection of a button cap caused by the torsional forces on the push button created by depression forces applied by the user at an edge of the push button. As a result, the dome switch provides a predictable and consistent positive tactile feedback to the user similar to that achieved by a centrally applied depression force.
