A key device includes a substrate, a key cap and a restoring member. The substrate includes a top surface and two pivot seats protruding on the top surface. The pivot seats are spaced from each other. Each pivot seat has an eave portion laterally extending from a top thereof. The eave portion has a bottom edge. The key cap is above the top surface. The key cap includes a side edge and two extending arms extending from the side edge. An end of each extending arm has a pivoting portion. The pivoting portions pivotally abut against the bottom edges of the eave portions respectively without contacting the top surface of the substrate. The restoring member is between the substrate and the key cap and abuts against a bottom of the key cap.

A touch button with better feel in pressing is disposed on a casing, including a touch board having a touch area and a press area, a fixing element disposed on a side of the touch board to form a difference in height from the touch board, an elastic connector for connecting the touch board with the fixing element and forming a state of elastic vertical displacement between the press area and the casing, and plural elastic supporters forming an elastic supporting force to the press area, thereby enabling the press area to manifest the state of elastic vertical displacement on the casing by the elastic supporting force.

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.
