A button mechanism for effecting user inputs to an electronic device. The button mechanism includes a frame top that has a rigid frame portion; and flexible frame portion. The button mechanism further includes a device body that is oriented substantially parallel to the frame top and a button assembly that is situated between the device body and the frame top. The button assembly includes a contact portion that is operable to provide an electronic signal to control circuitry for the electronic device. The button assembly is affixed to an upper portion of the device body. The mechanism further includes a switch attached to the button assembly on the contact portion and a spring portion having a stepwise shape. The spring portion has an upper horizontal step portion and a lower horizontal step portion. The lower horizontal step portion of the spring is affixed to the button assembly. The upper horizontal step portion is disposed above the switch and below the flexible frame portion such that, upon application of a downward pressure to the flexible frame, the upper horizontal step portion is deformed downward to bring the upper horizontal step portion in contact with the switch, causing an electronic signal to be sent to the control circuitry of the electronic device.
