Abstract
An apparatus to secure a sensor assembly for a device touch button (such as for a mobile communications device). A touch sensor slot forms a part of the device case interior at a back-side of the touch button surface, and is configured to position the touch sensor (such as a sense coil inductor) relative to the associated touch button. A touch sensor spring clip is inserted within the touch sensor slot to flexibly urge the touch sensor toward the front-side surface of the touch sensor slot (back-side of the touch button surface). The touch sensor can include front-side spacers to maintain a sensing gap between the touch sensor and the touch button surface, and can include a sensor stiffener at the back-side surface of the touch sensor assembly, the touch sensor spring clip contacting the sensor stiffener. The touch sensor assembly can comprise a flex circuit PCB assembly.
