Abstract: A circuit assembly for providing a switch sensor and a capacitive sensor. The circuit assembly has a first pattern of conductive material in a first plane and a second pattern of conductive material in a second plane. An insulating member in an intermediate plane separates the first and second patterns. In a switch sensor area, the insulating member has openings to allow a first conductive element in the first pattern to contact a second conductive element in the second pattern responsive a force being applied to the first conductive element. In the capacitive sensor area, the insulating member maintains spacing between conductive material in the first and second patterns. The circuit assembly also includes a preventative capacitance configuration that limits non-intentional capacitive coupling in the capacitive sensor area.

Abstract: The disclosure describes a button wheel. The button wheel comprises a support frame including a pair of parallel opposed inner surfaces. A platform is nestably mounted in the support frame. The platform includes a pair of parallel opposed outer surfaces forming a pair of linear bearings with the parallel opposed inner surfaces of the support frame to allow the platform to translate from a biased rest position in a direction parallel to the opposed inner surfaces and the opposed outer surfaces. The button wheel also includes first and second spaced apart mounts fixed to one of the support frame and said platform. The button wheel includes a shaft disposed along an axis and including a first end rotatably engaged in the first mount and a second end rotatably engaged in the second mount. A wheel is mounted on the shaft and a rotation sensor is in operative communication with the wheel. The button wheel also includes a translation sensor coupled between the support frame and the platform.
