1. A capacitive touch button comprising:
- a conductive key;
a first insulating layer that surrounds the conductive key and insulates capacitance from traveling to a metal body of a user device, which supports the capacitive touch button, if a user touches or is sufficiently close to touching the conductive key;
a conductive sensing layer;
a second insulating layer, wherein the conductive sensing layer is located between the first insulating layer and the second insulating layer, and wherein the conductive sensing layer includes a first portion in contact with the conductive key and a second portion in contact with a sensing pad; and
a switch, wherein the switch is located below the second insulating layer and the switch is configured to activate in response to the conductive key being depressed, and wherein the conductive sensing layer and the second sensing layer are made from a flexible material.

Abstract
A touch button comprising a conductive key; an insulating layer that surrounds a portion of the conductive key and insulates capacitance from traveling to a metal body of a user device, and conductive and sensing layers that are flexible. A user device that includes a power touch button that, when activated, allows a user to display quick-look information when the user device is in an idle state. A pre-defined image that includes the quick-look information may not occupy the entire area of a display. The display may be an organic light-emitting diode display.
